Answer 2

Solution:

Given:

=> Force = 500 N

=> Distance = 15 m

=> Time = 30 sec

To Find:

=> Power

Formula used:

=> Power = Force × velocity

Now, first we will calculate velocity.

=> Velocity = Distance ÷ Time

=> Velocity = 15 ÷ 30

=> Velocity = 0.5 m/s

Now, put the values in the power formula.

=> Power = Velocity × Force

=> Power = 0.5 × 500

=> Power = 250 watt.

Hence, power required is 250 watt.
