Answer:
30 Watts
Explanation:
Power is given by the formula P = W / t; where P is power, W is work, and t is time.
Work is given by the formula W = F x d; where F is the force, and d is the distance traveled.
Since we do not know the amount of work done, we have to calculate it:
W = F x d
W = (9 N) x (10 m)
W = 90 Nm (The unit for work is Newton-meters)
We now have the value for work, so we can calculate power:
P = W / t
P = (90 Nm) / (3 s)
P = 30 W (The unit for power is Watts)
