A 2-kg toy car accelerates from 0 to 5 m/s. A 2-kg toy car originally moving at 5 m/s is brought to rest.

A 2 kg toy car is held at a height of 3.75 m above the floor.

A 2-kg toy car accelerates from 5 to 10 m/s.

A 2-kg toy car accelerates from 10 to 5 m/s.

Carbon 14 is a naturally occurring stable

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?
