Agust of wind pushes a beach ball with a force of 9 newtons. the ball rolls 10 meters in 3 seconds. what is the power of the wind?

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)
