Decide if each description below is an example of a change caused by energy. From the drop-down menu, choose "IS" if it is an example of a change in energy and "IS NOT" if it is not an example of a change in energy.

The impact of a truck colliding at 16 km/h with a concrete pillar caused the bumper to indent only 7.4 cm. The truck stopped. Determine the acceleration of the truck during the collision.

This problem has been solved! See the answer The car's motion can be divided into three different stages: its motion before the driver realizes he's late, its motion after the driver hits the gas (but before he sees the police car), and its motion
