Answer to Question #123904 in Physics for Lacie

Question

The wind pushes a paper cup along the sand at a beach. The cup has a mass of 25kg and accelerates at a rate of 5m/s2. How much force is the wind exerting on the cup?

Answer 1

By the Newton's Second Law of Motion, we get:

$$F = ma = 25 \ kg \cdot 5 \ \dfrac{m}{s^2} = 125 \ N.$$

Answer:

$F = 125 \ N.$
