A ball thrown vertically upward reaches a maximum height of 30 meters above the surface of Earth. At its maximum height, the speed of the ball is

Answers

Answer:

0 m/s

Explanation:

In this problem,

A ball thrown vertically upward reaches a maximum height of 30 meters above the surface of Earth. We need to find the speed of the ball at the maximum height. When an object reaches its maximum height, after then it starts to decrease its speed. As a result, the speed of the ball will be equal to 0 m/s.

The speed of the ball thrown upwards is zero when the object reaches maximum height.

The given parameter:

maximum height, h = 30 m

The velocity of an object thrown upwards decreases with time because the object is moving against gravity, and the eventually becomes zero when the object reaches maximum height.

[tex]v_f = v_0 - gt= 0[/tex]

Thus, the speed of the ball thrown upwards is zero when the object reaches maximum height.

A 660 kg car is travelling around a circular track of radius 55.0 m at 11.5 m/s.
Calculate the force and its direction that provides the centripetal force acting on the car to keep it
in the circular path. (3 points)
a) 24 N toward the center of the circle
b) 24 N along the line tangent to the circle
c) 1.587 E3 N along the line tangent to the circle
d) 1.587 E3 N toward the center of the circle

Answers

Answer: D) 1.587 E3 N toward the center of the circle

This is the same as saying 1.587*10^3 newtons, or we can say 1587 newtons

=================================================

Work Shown:

m = mass = 660 kilograms

v = velocity = 11.5 meters per second

r = radius of circle = 55.0 meters

-------------

F = centripetal force = inward pulling force toward center of circle

F = (m*v^2)/r

F = (660*11.5^2)/55

F = 1587

F = 1.587 * 10^3

F = 1.587 E 3

The "E 3" notation is what many calculators display scientific notation to be

The units for the force here are in newtons.

The force is pulling on the object toward the center of the circle, which helps keep the car on the circular path, rather than it going off on a tangent.

An object of mass(0.8kg) is attached to massless string of length (2.0),and swung with a tangential velocity of (3.0m/s) what is the tension in the string?

Answers

Answer:

3.6 N

Explanation:

The magnitude of centripetal force in this case is equal to the magnitude of tension in the spring.

The formula is :

T= mv²/r ------where T is tension

m= mass of object =0.8 kg

v= velocity of object {tangential velocity} = 3.0 m/s

r= length of string = 2m

Applying the formula with real values;

T= mv²/r

T= {0.8 * 3²} / 2

T= { 7.2}/2 = 3.6 N

An object travels in a straight line for 1200 m at a velocity of 50 m/s, what is its time of travel?​

Answers

Given that,

distance = d = 1200m

velocity/speed = s = 50m/s

time = t

Also,

s = d/t

And,

t = d/s

t = 1200/50

t = 120/5

t = 24

Therefore, it takes 24s to travel.

Answer: Therefore, the travel time of a car that travels 1200 meters at 50 m/s is 24 seconds.

Explanation:

An object travels in a straight line for 1200 m at a velocity of 50 m/s, what is its time of travel?​

Data:

d = 1200 m

V = 50 m/s

t = ?

The formula for uniform motion is:

V = d/t

Where

V = speedd = distancet = time

We clear the formula for time t:

t = d/v

t = (1200 m)/(50 m/s)

t = 24 s

Therefore, the travel time of a car that travels 1200 meters at 50 m/s is 24 seconds.

Answers

Answer:

100 Nm and 25Nm/s.

Explanation:

Given the following data;

Force = 25N

Distance = 4m

Time = 5secs

To find the workdone;

Workdone = force * distance

Substituting into the equation, we have;

Workdone = 25*4

Workdone = 100 Nm

To find the power consumed;

Power = workdone/time

Substituting into the equation, we have;

Power = 100/4

Power = 25Nm/s

The work done on the box is 100 Nm, and the power is 25 Nm/s.

In a classic experiment, a ball (Ball 1) is dropped from a specific height. At the same
time, an identical ball (Ball 2) is launched horizontally from the same height. Which
ball hits the ground first?


A.) The dropped ball (Ball 1) because its path is shorter,

B.) The launched ball(Ball 2) because the ball's velocity is greater.

C.) The two balls will reach the ground at the same time because the horizontal and vertical planes of motion are independent of each other and they were also released from the same height.

D.) It is not possible to determine which ball hits the ground first because of the complex nature of motion

Answers

Answer: C

Explanation:

Gravity is acting equally on both objects causing the same vertical velocity because they are the same objects. The object launched horizontally off a cliff has a longer range because of the greater initial horizontal velocity

The answer to the question related to the time for two balls to reach the ground is option C, the two balls will reach the ground at the same time because the horizontal and vertical planes of motion are independent of each other, and they are also released from the same height.  

When a ball is dropped, knowing the height we could find the time with the following equation:

[tex] y_{f} = y_{i} + v_{i_{y}}t - \frac{1}{2}gt^{2} [/tex] (1)

Where:

[tex] y_{f} [/tex]: is the final height

[tex] y_{i} [/tex]: is the initial height

[tex]v_{i_{y}}[/tex]: is the initial speed of the ball in the vertical direction = 0 (it is dropped)

g: is the acceleration due to gravity

When the ball is launched horizontally from the same height, we could find the time with equation (1) since the acceleration in the horizontal direction is zero and the initial velocity in the vertical direction is also zero.

The horizontal motion is related to the equation:

[tex] x = v_{i_{x}}*t [/tex]   (2)

We can notice in both cases that the ball is accelerated only by gravity.

Let's evaluate each statement

A) This statement is incorrect because the path is the same for both cases. The ball is dropped and launched from the same height.

B) This statement is also incorrect. The velocity of the dropped ball is the same as the velocity of the launched ball because the ball is accelerated only by gravity.

C) This statement is correct. We can see that we would get the same time in equation (1) since [tex]v_{i_{y}}[/tex], [tex]y_{f}[/tex], and [tex]y_{i}[/tex] is the same for the dropped ball and the launched ball.  

D) This statement is incorrect. The nature of motion is related to a freefall motion in both cases.  

Therefore, the answer is option C.

lift the shark from rest. If the shark's acceleration while being lifted equals

Answers

Answer:

m = 20,000 kg

Explanation:

Force, [tex]F=2.5\times 10^4\ N[/tex]

Acceleration of the shark, [tex]a=1.25\ m/s^2[/tex]

It is required to find the mass of the shark. Let m is the mass. Using second law of motion to find it as follows :

F = ma

Putting the value of F and a to find m

[tex]m=\dfrac{F}{a}\\\\m=\dfrac{2.5\times 10^4}{1.25}\\\\m=20,000\ kg[/tex]

So, the shark's mass is 20,000 kg.
