A remote-control car has batteries that store 1.8 kJ of energy. When the car is

driven across a sports field there is friction dragging on the car, producing a force
of 2 N.
Complete the following sentence: If the car is 100% efficient , it could travel a
distance of ……….metres on a single battery charge.

Answer 1

If the car is 100% efficient , it could travel a

distance of 900 metres on a single battery charge.

1800 J = 2 N•d m

d = 900 m
