Answer:
The magnitude of force exerted on the handle is 108.73 N
Step-by-step explanation:
To determine the magnitude of force exerted, we will use the formula relating Power and Force.
Power is the rate at which work is done. Power can be calculated from the formula
Power = Work / Time
But, Work = Force × Distance
Hence,
Power is given by the formula

Where P is the Power
F is the force
s is the distance
and t is the time
From
,
Then we can write that

From the question,
Distance, s = 1.1 m
Time, t = 1.3 s
Power, P = 92 W
Putting these values into the formula, we get



Hence, the magnitude of force exerted on the handle is 108.73 N.
