Question

1. the wind pushes a paper cup along the sand at a beach. the cup has a mass of 0.25 kg and accelerates at a rate of 5 m/s². how much force is the wind exerting on the cup?

Explanation:

Step1: Identify the formula

We use Newton's second - law $F = ma$, where $F$ is force, $m$ is mass and $a$ is acceleration.

Step2: Substitute the values

Given $m = 0.25$ kg and $a=5$ m/s². Substitute into the formula: $F=(0.25)\times(5)$.

Step3: Calculate the force

$F = 1.25$ N.

Answer:

$1.25$ N
