An object's inertia is its tendency to maintain contact:
Gala2k [10]

hello! it is velocity.

i say this because, Inertia is the tendency of an object to resist changes in its state of motion. ... The state of motion of an object is defined by its velocity - the speed with a direction.

A Ping-Pong ball moving East at a speed of 4 m/s collides with a stationary bowling ball. The Ping-Pong ball bounces back to the
In-s [12.5K]

Answer:

They experience the same magnitude impulse

Explanation:

We have a ping-pong ball colliding with a stationary bowling ball. According to the law of conservation of momentum, we have that the total momentum before and after the collision must be conserved:

p_i = p_f\\p_p + p_b = p'_p+p'_b

where

p_p is the initial momentum of the ping-poll ball

p_b is the initial momentum of the bowling ball (which is zero, since the ball is stationary)

p'_p is the final momentum of the ping-poll ball

p'_f is the final momentum of the bowling ball

We can re-arrange the equation as follows

p_p - p'_p = p_b'-p_b

or

-\Delta p_p = \Delta p_b

which means

|\Delta p_p | = |\Delta p_b| (1)

so the magnitude of the change in momentum of the ping-pong ball is equal to the magnitude of the change in momentum of the bowling ball.

However, we also know that the magnitude of the impulse on an object is equal to the change of momentum of the object:

I=\Delta p (2)

Therefore, (1)+(2) tells us that the ping-pong ball and the bowling ball experiences the same magnitude impulse:

|I_p| = |I_b|
