Question

you give a shopping cart a shove down the aisle. the cart is full of groceries and has a mass of 50 kg. the cart accelerates at a rate of 3 m/s2. how much force did you exert on the cart?

Explanation:

Step1: Identify the formula

Newton's second law: $F = ma$ (where $F$ is force, $m$ is mass, $a$ is acceleration)

Step2: Substitute the values

Given $m = 50$ kg and $a=3$ m/s². So $F=(50)(3)$

Step3: Calculate the force

$F = 150$ N

Answer:

150 N
