If the net force acting on a moving object CAUSES NO CHANGE IN ITS VELOCITY, what happens to the object's momentum?
SOVA2 [1]

If the net force acting on a moving object causes no change in its velocity, the object's momentum will stay the same.

<h3>What is momentum?</h3>

Momentum of a body in motion refers to the tendency of a body to maintain its inertial motion.

The momentum is the product of its mass and velocity.

This suggests that if the net force acting on a moving object causes no change in its velocity, the momentum of the object will remain the same.

Therefore, if the net force acting on a moving object causes no change in its velocity, the object's momentum will stay the same.

What is the mass of a block concrete that gains 52,800 joules of energy when its temperature is increased by 5 degrees Celsius s
valina [46]

Answer:

12 kg

Explanation:

q = 52,800 J

c = 880 J/(kg * K) Pretty sure you missed the kg here

ΔT = 5 °C = 5 K (reminder that this only applies to ΔT and not T)

q = mcΔT ⇒ m = q/(cΔT) = 52,800 J / (880 J/(kg * K) * 5 K) = 12 kg

. If block A has a velocity of 0.6 m/s to the right, determine the velocity of cylinder​
andrezito [222]

Answer:

As we can see, a string is attached with block A, and three string is folded with ply which is attached with B

x  

B

​  

=3x  

A

​  

 

Now differentiate with respect to x

V  

B

​  

=3V  

A

​  

 

Given,

V  

A

​  

=0.6m/s(totheright)

So,

V  

B

​  

=0.6×3

=1.8m/s(downward)

The acceleration of a particle is given by a = 3t – 4, where a is in meters per second squared and t is in seconds. Determine th
Genrish500 [490]

Answer:

v=0.04m/s\\

s=-28.592m\\

Explanation:

a = 3t-4

v(t)=\int\limits^t_0 {a(t)} \, dt =3/2*t^{2}-4t+v_0\\

if t=3.6s and initial velocity, v0,  is -5m/s

v=0.04m/s\\

s(t)=\int\limits^t_0 {v(t)} \, dt =1/2*t^{3}-2t^{2}+v_0*t+s_0\\

if t=3.6s and the initial displacement, s0, is -8m:

s=-28.592m\\
