The wind pushes a paper cup along the sand at a beach. the cup has a mass of 0.025kg and accelerates at a rate of 5m/s2 how much force is the wind exerting on the cup

Mass of the paper cup = 0.025 kg

Rate of acceleration of the cup due to force of wind = 5 m/s^2

We already know that

Force = Mass * Acceleration

So Force exerted by the wind on the cup = 0.025 * 5 kg m/s^2

= 0.125 Newton

So the force exerted by the wind on the paper cup is 0.125 newton. I hope this is the answer that you wanted and the process of doing such problems is clear to you.
