Question

1. George Eliot pulls on a curtain string. If the curtain has a mass of 1.2 kg and she can pull

it so that it accelerates at a rate of 4 m/s2, what is the force she exerts on the curtain
string?

Answer 1

F = 4.8 N

Step-by-step explanation:

Given that,

Mass of the curtain, m = 1.2 kg

Acceleration of the pull, a = 4 m/s²

We need to find the force she exerts on the curtain.

We know that,

F = ma

Put al the values,

F = 1.2 kg × 4 m/s²

= 4.8 N

So, the force is 4.8 N.
