At a baseball game, a pitcher throws the ball at 41.01 m/s to the catcher at home plate. If the mass of the baseball is 0.1299 kg, what impulse is required to provide the baseball with that much momentum?

Answer:

190

Explanation:

add because your looking for the Miles

When a  person walks 60.0m and then walks 130m then the displacement of the person would be 70 meters if he first walked east and then west.

An object's position changes if it moves in relation to a reference frame, such as when a passenger moves to the back of an airplane or a professor moves to the right in relation to a whiteboard. Displacement describes this shift in location.

As given in the problem a person walks 60.0m and then walks 130m and if he first walks east then west then we have to find the displacement.

Displacement = final position -initial position

Lets us consider eastward as positive direction,

displacement = 60 - 130

                       = -70 meters

The negative sign represents the displacement would be in a westward direction.

Thus, If a guy initially went east and then west, his displacement would be 70 meters when he traveled 60.0 meters and then 130 meters.

The Volume of a Rectangular Prism

A rectangular prism is also called a rectangular box and has three dimensions all perpendicular to each other.

Given a rectangular prism of length L, width W, and height H, the volume is calculated as:

V = WLH

We are given the dimensions of a rectangular box: L= 4 cm, W = 2 cm, H = 2 cm. Computing the volume:

V = 2 cm * 4 cm * 2 cm

Answer:

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.

Explanation:

Answer:

Speed refers to the distance taken at a specific time interval. Velocity is the speed in a certain direction.

Answer:

(4) The particle travels with a constant velocity until t0 and then comes to rest.

Explanation:

Uniform rectilinear motion is defined as the motion of a particle in a straight line with constant velocity, that is, there is no change in velocity over time.

And this can be determined by means of the following equation:

[tex]x=x_{o}+v*(t-t_{o})[/tex]

where:

x = final point [m]

xo = initial point [m]

v = velocity (slope) [m/s]

t = final time [s]

to = initial time [s]

So the slope in the graph gives the constant velocity

[tex]v=\frac{x-x_{o}}{t-t_{o}}[/tex]

Therefore, after the time to there is no displacement, that is the particle comes to rest.

Choice-D is the only velocity on the list.

(It has a speed and a direction.)

The jet's velocity might be represented by  700 km/h west. Hence, option (D) is correct.

The rate at which a body's displacement changes in relation to time is known as its velocity. Velocity is a vector quantity with both magnitude and direction. SI unit of velocity is meter/second.

In this question, 700 h/km, 700 km have different unit that of velocity. So, option (A) and option (B) is not correct. . 700 km/hr has same unit that of velocity.  But it does not has direction. So, option (C) is also incorrect.  700 km/h west has the same unit of velocity with define direction. So, option (D) is correct.

Hence option (D) is correct answer.

Answer:

Explanation:

Answer:

-11,813.87N

Explanation:

According to coulombs law, the Force between the two charges is expressed as;

F = kq1q2/d²

k is the coulombs constant = 9*10⁹kg⋅m³⋅s⁻²⋅C⁻².

q1 = -0.00067 C

q2 = 0.00096 C

d  = 0.7m

Substitute into the formula:

F =  9*10^9 *  -0.00067 * 0.00096/0.7²

F = 9*10⁹*-6.7*10⁻⁴*9.6*10⁻⁴/0.49

F = -578.88*10⁹⁻⁸/0.49

F = -578.88*10/0.49

F = -5788.8/0.49

F = -11,813.87N

Hence the force between the two charges is -11,813.87N

Explanation:

Any object or agent (biological, chemical, radiological, and/or physical) that has the potential to harm people, animals, or the environment is considered a hazardous material.

This may be the result of the material's own properties or its interactions with other substances. The U.S. Environmental Protection Agency (EPA), the U.S. Occupational Safety and Health Administration (OSHA), the U.S. Department of Transportation (DOT), and the U.S.

Nuclear Regulatory Commission are primarily responsible for defining and enforcing laws and regulations related to hazardous materials (NRC). Each defines "hazardous substance" differently.

This includes chemicals such as carcinogens, irritants, corrosives, toxic agents, sensitizers, agents that damage the lungs, skin, eyes, or mucous membranes; chemicals that can combust, explode, are flammable, oxidizers, pyrophorics, unstable-reactive or water-reactive.

Therefore, Any object or agent (biological, chemical, radiological, and/or physical) that has the potential to harm people, animals, or the environment is considered a hazardous material.

Explanation:

Newton's third law.

Answer:

T_finalmix = 45 [°C].

Explanation:

In order to solve this problem, a thermal balance must be performed, where the heat is transferred from water with the highest temperature, to the water with the lowest temperature, so the final temperature of the mix must be equal once the thermal balance is achieved.

[tex]Q_{water}=Q_{methanol}[/tex]

where:

[tex]Q_{water}=m_{water}*Cp_{water}*(T_{waterinitial}-T_{final})[/tex]

mwater = mass of the water = 300 [g] = 0.3 [kg]

Cp_water = specific heat of the water = 4180 [J/kg*°C]

T_waterinitial = initial temperature of the water = 80 [°C]

T_finalmix = final temperature of the mix [°C]

[tex]Q_{water}=m_{water}*Cp_{water}*(T_{final}-T_{water})[/tex]

Now replacing:

[tex]0.3*4180*(80-T_{final})=0.3*4180*(T_{final}-10)\\100320-1254*T_{final}=1254*T_{final}-12540\\112860=2508*T_{final}\\T_{final}=45[C][/tex]

The final temperature of the mixture is 45 °C

Heat lost by warm water = Heat gained by cold water

Qᵥᵥ = Q꜀

MᵥᵥC(Tᵥᵥ – Tₑ) = M꜀C(Tₑ – T꜀)

0.3 × 4180 × (80 – Tₑ) = 0.3 × 4180 × (Tₑ – 10)

1254 (80 – Tₑ) = 1254(Tₑ – 10)

Clear bracket

100320 – 1254Tₑ = 1254Tₑ – 12540

Collect like terms

100320 + 12540 = 1254Tₑ + 1254Tₑ

112860 = 2508Tₑ

Divide both side by 2508

Tₑ = 112860 / 2508

Tₑ = 45 °C

Thus, the final temperature of the mixture is 45 °C

Answer:

b. 60 (kg*m)/s

c. 3 m/s

Explanation:

Givens:

m = 20 kg

v_i = 0 m/s

t = 10 s

F = 6 N

a) Impulse:

I = F*t

I = 6 N*10 s

I = 60 N*s

b) Momentum:

p = v*m

F = m(a)

a = F/m

a = 6 N/20 kg

a = 0.3m/s^2

a = (v_f -v_i)/t

v_f = (0.3 m/s^2)*10 s

v_f = 3.0 m/s

p = 3 m/s*20 kg

p = 60 (kg*m)/s

c. Final velocity

a = (v_f -v_i)/t

v_f = (0.3 m/s^2)*10 s

v_f = 3.0 m/s

The impulse, momentum and final velocity can all be obtained from Newton's second law.

Let us recall that the impulse is obtained as the product of force and time.

Impulse = Force × time

Impulse = 6 N × 10 s = 60 Ns

From Newton's second law of motion;

F.t = mv - mu

Since the object was initially at rest;

F.t = mv

Hence, the final velocity of the object is 60 Kgms-1

The final velocity is obtained from;

F.t = mv

v = F.t/m
