Question 1 Report
A body is pulled over a distance of 500m by a force of 20N. If the power developed is o.4 kW, calculate the time interval during which the force is applied
Answer Details
Power, P = work done (W) / time interval (t)
We know that, work done (W) = force (F) x distance (d)
Therefore, power (P) = (F x d) / t
Rearranging this equation, we get:
t = (F x d) / P
Substituting the given values, we get:
t = (20 N x 500 m) / 0.4 kW
t = 25,000 s
Therefore, the time interval during which the force is applied is 25,000 seconds.
