Question
An ox can apply a maximum force of 1000 N. It is taking part in a cart race and is able to pull the cart at a constant speed of 30 ms-1 while making its best effort. Calculate the power developed by the ox.
Solution
Given, force = 1000 N, velocity = 30 m/s-1
Power, P = Force × Velocity
P = 1000 × 30 = 30,000 W = 30 kW
