Explanation:
The force applied by the man is 15 N to push the wheel through 10 m
Thus the work done by him = Force x distance
= 15 x 10 = 150 J
The time taken can be found by the relation = t = [tex]\frac{Work}{Power}[/tex]
Therefore t = [tex]\frac{150}{30}[/tex] = 5 s
Answer:5 seconds
Explanation:
Power=30w
Force=15N
Distance=10m
Time=?
Power=(force x distance)/time
30=(15 x 10)/time
time=(15 x 10)/30
time=150/30
time=5
time=5 seconds
