Question

A student is helping her teacher move a 9.5 kg box of books. What net sideways force must she exert on the box to slide it across the floor so that is accelerates at 1.0m/s2?

Answer 1

As we know that mass of the box is given as

m = 9.5 kg

acceleration of the box is given as

$a = 1 m/s^2$

so by Newton's II law we can say

$F = ma$

now we can substitute all the values in it

$F = 9.5 \times 1$

$F = 9.5 N$

So it required 9.5 N force to slide it
