Question

1. a cart loaded with books is being pushed down the hallway. if the cart has a mass of 12 kg, how much force is required to accelerate the cart to 1.5 m/s²?

Explanation:

Step1: Recall Newton's second law

Newton's second law is $F = m \times a$, where $F$ is force, $m$ is mass, and $a$ is acceleration.

Step2: Identify given values

Mass $m = 11.2\ \text{kg}$, acceleration $a = 1.5\ \text{m/s}^2$

Step3: Calculate the force

Substitute values into the formula:
$F = 11.2 \times 1.5$

Answer:

$16.8\ \text{N}$
