Question

A motorbike engine can develop a power of 90000 W in order to keep a constant velocity of 30m/s. What is the pushing force?

Answer 1

Answer:

Explanation:

Power = force × velocity

Force = 90000/30

Force= 3000N

Answer 2

Given: Power of the motorbike, P = 90,000 W

           Velocity, v = 30 m/s

To Find: pushing force, F.

Solution:

To calculate F, the formula used:

• Power = Force x Velocity
• P = F x v

Applying the above formula:

P = F x v

90,000 = F x 30

F = 90,000 / 30

  = 9000 / 3

  = 3000

F = 3000 N

Hence, the pushing force is 3000 newtons.
