Question 3

A mover pushes a box with 400N a distance of 3m in 55s.
a -Calculate the work:
b- Calculate the Power

Answer 1

1200J

21.8Watts

Step-by-step explanation:

Given parameters:

Force = 400N

Distance = 3m

Time = 55s

Unknown:

Work done = ?

Power = ?

Solution:

Work done is the force applied to move a body through a certain distance.

Power is the rate at which work is done

Work done = Force x distance = 400 x 3 = 1200J

Power =
`(work done )/(time)` =
`(1200)/(55)` = 21.8Watts
