Question

What force must be applied to a body through a distance of 10 m such that it does a work of 4000 j if the mass of body is 20 kg what is the acceleration of the body​

Answer 1

$\sf \huge \fcolorbox{red}{pink}{Solution :)}$

Given ,

• Displacement = 10 m
• Work = 4000 J
• Mass = 20 kg

We know that ,

$\large \sf \fbox{WORK = FORCE × DISPLACEMENT }$

It can be written as ,

$\large \sf \fbox{WORK = MA × DISPLACEMENT }$

Substitute the known values , we get

4000 = 20 × A × 10

A = 4000/200

A = 20 m/s²

Hence , 20 m/s² is the acceleration of the body
