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*5 \\ =0.125\text{ N} \end{gathered}`

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