A 125 W motor accelerates a block along a level, frictionless surface at an average speed of 5.0

Lelu [443]

Answer:

25N

Explanation:

Given parameters:

Power of the motor = 125W

Average speed = 5m/s

Unknown:

Force supplied to the motor = ?

Solution:

Work done is the force applied to move a body through a particular distance;

Work done = Force x distance

Also,

Work done = Power x time

So;

Force x distance = Power x time

since force is the unknown;

Force = $\frac{Power x time}{distance}$

Speed = $\frac{distance }{time}$

Force = $\frac{Power}{speed}$

Now solve;

Force = $\frac{125}{5}$ = 25N
