Answer:
Power, P = 80 watts
Explanation:
Given,
The force acting on the box, F = 20 N
The displacement of the box, s = 8 m
The time taken by the box to cover the distance is, t = 2 s
The work done on the box is given by the formula,
W = F x S
Substituting the given values in the above equation,
W = 20 x 8
= 160 J
The rate of doing work is defined as the power,
P = W / t
= 160 / 2
= 80 watts
Hence, the power is, P = 80 watts.
