Question 33

A mobility scooter speeds up along a level path. Its constant driving force acts in the direction of motion for 8.0 m. Of the work done by this force, 480 J is transferred to the scooter's kinetic energy store and 160 J is transferred to thermal energy stores. What is the driving force?
