The rate at which energy must be supplied to the car is 700 W.

Instantaneous power

The instantaneous of an object is the rate at which energy is supplied at a given period of time.

P = Fv

where;

  • P is the instantaneous power
  • F is applied force
  • v is the speed

The rate at which energy must be supplied to the car is calculated as follows;

P = 70 x 10

P = 700 W
