Question

3. The wind pushes a paper cup along the sand at a beach. The cup has a mass of0.025 kg and accelerates at a rate of 5 m/s?. How much force is the wind exerting onthe cup?

Answer 1

Given data

*The mass of the cup is m = 0.025 kg

*The given acceleration is

$a=5m/s^2$

The expression for the force exerting by the wind on the cup is given as

$F=ma$

Substitute the values in the above expression as

$\begin{gathered} F=0.025\times5 \\ =0.125\text{ N} \end{gathered}$

Thus, the force exerted by the wind on the cup is F = 0.125 N
