Solution:

Concept:

Power is the rate of doing work, which equals force multiplied by velocity for a constant speed.

Explanation:

The engine supplies power

P

to keep the vehicle moving at constant speed

V

Power is given by:

P = F \times V

Rearranging to make force

F

the subject:

F = \frac{P}{V}
