A 2-kg toy car accelerates from 0 to 5 m/s2. It travels 2 m.

A 2-kg toy car originally moving at 5 m/s is
brought to rest. It travels 1 m.

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/s2. It
travels 7 m.

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

Answer choices:
20 joules of work is done by the object

No work is done on or by the object

10 joules of work is done by the object

100 joules of work is done by the car

70 joules of work is done by the car
