A 2500 kg truck moving at 10.00 m/s strikes a car of mass 1000 kg waiting at a traffic light, hooking bumpers. The two continue to move together at a velocity of

4.0 m/s

7.1 m/s

10 m/s

12 m/s

What type of collision is this?

elastic

inelastic

Perfectly elastic

perfectly inelastic

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

because if the tool that you are using is not balanced it there would be false mass.
