you give a shopping cart a shove down the aisle. the cart is full of groceries and has a mass of 15 kg. the cart accelerates at a rate of 3 m/s². how much force did you exert on the cart?

Answer

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 $m = 15\ kg$ and $a=3\ m/s^{2}$, so $F=15\times3$.

Step3: Calculate the force

$F = 45\ N$.

Answer:

$45\ N$
