Answer:

[tex]\boxed {\boxed {\sf a= -7 \ m/s^2}}[/tex]

Explanation:

Acceleration is the change in velocity over time.

[tex]a= \frac {v_f-v_i}{t}[/tex]

The object accelerates from 45 meters per second to 10 meters per second in 5 seconds. Therefore,

[tex]v_f=10 \ m/s \\v_i= 45 \ m/s \\t= 5 \ s[/tex]

Substitute the values into the formula.

[tex]a= \frac{ 10 \ m/s - 45 \ m/s}{5 \ s}[/tex]

Solve the numerator.

[tex]a= \frac { -35 \ m/s}{5 \ s}[/tex]

Divide.

[tex]a= -7 \ m/s/s[/tex]

[tex]a= -7 \ m/s^2[/tex]

The acceleration of the object is -7 meters per square second. The acceleration is negative because the object's velocity decreases and the object slows down.

What is the magnitude of the boat’s resultant velocity? Round your answer to the nearest whole number.

answer :  25.73 m/s

Explanation:

Given

V1 = 15 miles/hour =  6.71 m/s [ 45° EN ]

V2 = 18 m/s [ 5° NE ]

Calculate  the resultant velocity

Vr = 6.71 m/s[45°] + 18m/s[5°].

Vr = ( 6.71 *Cos45° + 6.71 *sin45°) + ( 18 *Cos5° + 18*sin5° )

Vr = ( 4.74  + 4.74 i  )+  ( 17.93 + 1.57i) = 22.67 + 12.18i.

Therefore the magnitude

= [tex]\sqrt{22.67^2 + 12.18^2}[/tex] = 25.73 m/s

When you get out of bed in a morning it's most likely too be cold so your bare feet on a floor not carpet a bare floor will feel cold since the temperature and molecules had changed and if you step on a warm fuzzy rug it will feel warm since your feet are cold and the rugs fuzziness or material keeps you warn

We feel more cold on feet on morning because heat from our feet will flow to the cold floor. We feel more cold on the bare floor than the rug since it conducts heat away from our feet.

Heat will be transfer on a temperature gradient from one substance to the other.  Heat is transferring from the hot body to the colder body. There are three types of heat transfer are there namely, conduction, convection and radiation.

Conduction is the heat transfer in solids , convection in liquids and radiation is the heat or energy transfer mode in gases and vacuum.  At the morning, the floor will be more cool whereas our body will be hotter, thus heat will flow our body to floor make our feet cool.

A bare floor will conduct thermally more than a rug do. Thus the bare floor conducts heat away from our feet and make our feet more cool.

Answer:

The correct answer is: 0°C + 0°C = 32°F

Explanation:

We need to remember the conversion equation from Celsius to Fahrenheit:

[tex]y^{\circ}F=(x^{\circ}C * \frac{9}{5})+32[/tex]

In our case x = 0, then y will be:

[tex](0^{\circ}C * \frac{9}{5})+32=32[/tex]

[tex]y=32^{\circ}F[/tex]

Now 0°C + 0°C is just 0°C because if we add a body at a certain temperature to another body with the same temperature the total temperature will the same.

Then, knowing that 0°C = 32°F we can conclude that:

[tex]0^{\circ}C+0^{\circ}C=32^{\circ}F[/tex]

A roller coaster is released from the top of a track that is 125 m high. Find the roller coaster speed when it reaches ground level. 75. A 1500 kg car, moving at a speed of 20 m/s comes to a halt. How much work was done .

The roller coaster speed when it reaches to ground level is 15.65 m/sec

Given-

Roller coaster is released at a height of 125 meters.

It is known that, square of the final velocity [tex]v[/tex] of the body is equal to the sum of the square of initial velocity [tex]v_{10}[/tex] and the product of the twice of acceleration [tex]a[/tex] and displacement [tex]d[/tex]. It can be written as,

[tex]v^{2} =v_{0}^2+2ad[/tex]

Roller coaster released from rest therefore initial velocity is zero.

[tex]v^{2} =0+2ad[/tex]

[tex]v^{2} =2ad[/tex]

Roller coaster will fall towards the ground with an acceleration equal to gravity g and height of 125 m. therefore,

[tex]v^{2} =2\times g\times 125[/tex]

[tex]v^{2} =2\times 9.8\times 125[/tex]

[tex]v^{2} =2450[/tex]

[tex]v=15.65[/tex]

Hence, the roller coaster speed when it reaches to ground level is 15.65 m/sec.

Answer:

a change of position in relation to another object.

Explanation:

Motion can be defined as a change in the location (position) of a physical object or body with respect to a reference point.

This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.

A reference point refers to a location or physical object from which the motion (movement) of another physical object or body can be determined.

Mathematically, the motion of an object is described in terms of acceleration, time, distance, speed, velocity, displacement, position, etc.

Hence, motion is a change of position in relation to another object.

Answer:

The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

Answer:

85.8 m/s

Explanation:

We know that the length of the circular path, L the plane travels is

L = rθ where r = radius of path and θ = angle covered

Now,its speed , v = dL/dt = drθ/dt = rdθ/dt + θdr/dt

where dθ/dt = ω = angular speed = v'/r where v' = maximum speed of plane and r = radius of circular path

Now, from θ = θ₀ + ωt where θ₀ = 0 rad, ω = angular speed  and t = time,

θ = θ₀ + ωt = 0 + ωt = ωt

So, v = rdθ/dt + θdr/dt

v = rω + ωtdr/dt

v = (r + tdr/dt)ω

v = (r + tdr/dt)v'/r

v = v' + tv'/r(dr/dt)

v = v'[1 + t(dr/dt)/r]

Given that v' = 110 m/s, t = 33.0s, r = 120 m and dr/dt = rate at which line is shortened = -0.80 m/s (negative since it is decreasing)

So, v = 110 m/s[1 + 33.0 s(-0.80 m/s)/120 m]

v = 110 m/s[1 + 11.0 s(-0.80 m/s)/40 m]

v = 110 m/s[1 + 11.0 s(-0.02/s)]

v = 110 m/s[1 - 0.22]

v = 110 m/s(0.78)

v = 85.8 m/s

Answer:

The combined velocity of Sally and the sled is 1.688 meters per second.

Explanation:

Let suppose that Sally collides inelasticly, meaning that final velocity of Sally-sled system can be determined solely by Principle of Momentum Conservation:

[tex]m_{S}\cdot v_{S, o} + m_{s}\cdot v_{s,o} = (m_{S}+m_{s})\cdot v[/tex] (1)

Where:

[tex]m_{S}[/tex] - Mass of Sally, measured in kilograms.

[tex]m_{s}[/tex] - Mass of the sled, measured in kilograms.

[tex]v_{S,o}[/tex] - Initial velocity of Sally, measured in meters per second.

[tex]v_{s,o}[/tex] - Initial velocity of the sled, measured in meters per second.

[tex]v[/tex] - Final velocity of the Sally-sled system, measured in meters per second.

If we know that [tex]m_{S} = 54\,kg[/tex], [tex]m_{s} = 10\,kg[/tex], [tex]v_{S,o} = 2\,\frac{m}{s}[/tex] and [tex]v_{s,o} = 0\,\frac{m}{s}[/tex], then the final velocity of the system is:

[tex]v = \frac{m_{S}\cdot v_{S,o}+m_{s}\cdot v_{s,o}}{m_{S}+m_{s}}[/tex]

[tex]v = 1.688\,\frac{m}{s}[/tex]

The combined velocity of Sally and the sled is 1.688 meters per second.

Explanation:

Answer:

A. A train traveling 60 miles per hour.

Explanation:

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

[tex] Momentum = mass * velocity [/tex]

This ultimately implies that, the mass of an object or body is directly proportional to its momentum. Thus, the higher the mass of an object or body, the greater would be its momentum and vice-versa.

Hence, a train traveling 60 miles per hour would have the most momentum because it has the greatest mass among the other objects (options).
