Question 47

An engine of power P P\,P exerts a constant force F F\,F on a vehicle. The vehicle moves a distance d d\,d during the time t t\,t that the force acts.

Which equation is used to calculate the distance ddd?

A

d=FtPd = \frac{F t}{P}d=PFt​

B

d=PtFd = \frac{P t}{F}d=FPt​

C

d=PFtd = \frac{P}{F t}d=FtP​

D

d=FPtd = \frac{F}{P t}d=PtF​
