A man pushes a box of mass `50kg` with a force of `80N`. What will be the acceleration of the box? What would be the acceleration if the mass were halved?

Text Solution

Verified by Experts

Here `m=50g, F=80N, a=?`
From `F=ma, a=F/m=80/50=1.6 ms^-2`
When mass is halved , acceleration would become twice.
New acceleration `=2 times 1.6=3.2 ms^-2`

A man of mass 80kg pushes a box of mass 20kg horizontally. The man moves the box with a constant acceleration of 2m//s^(2) but his foot does not slip on the ground. There is no friciton between the box and the ground, whereas there is sufficient friction between the man's foot and the ground to prevent him from slipping. Assertion :- The force applied by the man on the box is equal and opposite to the force applied by the force applied by the box on the man. Reason :- Friction force applied by the ground on the man is 200N .
