A 3kg ball moving at 8m/s strikes a 2kg ball at rest. After the collision, the 3kg ball is moving with a velocity of 4m/s. What is the velocity of the 2kg ball after the collision?

gravititional force is a force that is acting around you, it is non-contactable and it is a force that pulls you to the core of the earth.

brainliest

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.

3. dark matter

empty space could also be a simple vacuum
