Answer:
Power = 7.5 watt
Explanation:
Given data:
Power expend = ?
Force applied = 10 N
Distance cover = 1.5 m
Time = 2 s
Solution:
Power = work/ time
First of all we will calculate work.
Work = Force × distance
Work = 10 N × 1.5 m
Work = 15 N.m
Now we will calculate the power.
Power = 15 N.m / 2s
N.m/s = 1 watt
Power = 7.5 watt
