Solution

The correct option is A 20kw
Given Tension = 2000 N , and velocity = 10 m/s.
Power exerted in the trailor= Workdone/Time
Work done = Force x Displacement
Power= (Force x Displacement)/Time
Also Velocity = Displacement/Time
Thus Power= Forcex Velocity
= 2000 N x 10 m/s
= 20000 N m/s
= 20 KW
