Q

Which of the following best describes why the occupants of a vehicle moving at 50 miles per hour will be injured when the vehicle strikes a tree but not when it brakes to a stop?

A

The energy gradually dissipates as heat due to the friction of braking, rather than transferring to the vehicle and its occupants.
