Question

7. (6 points) A 4.5 kg mass moving at 15 m/s hits a stationary 8.5 kg mass...
after they collide, the 4.5 kg mass bounces in the reverse direction with a
speed of 11.0 m/s. What is the speed of the 8.5 kg mass after the
collision?​

Answer 1

Answer:

The speed of 8.5kg mass is zero

Explanation:

Because in this case a lighter body hits heavier one so lighter body will move twice its speed while the heavy body remains at its position
