Question

Aforce of 240N keeps a 900 kg car moving at a constant velocity of 10m/s . Calculate the rate at which the car's engine supplies energy?

Answer 1

GIVEN:-

Force = 240N

Velocity (also can be taken as time) = 10m/s

TO FIND:-

=>The energy

UNDERSTANDING THE CONCEPT:-

According to the question, we know the force and velocity. By this given information we can calculate energy by using

E = F × V

This is nothing but E = Power × Time.

ANSWER:-

E = 240 × 10

E = 2400W

Therefore, the rate at which the car's engine supplies energy.

Some Basic Knowledge:

=>The velocity of an object is the rate of change of its position with respect to a frame of reference.

=> Force is the push or pull of an object.

=> Energy is the capacity of doing work.
