Question

A ball of mass 5kg is sliding on a plane with initial velocity of 10m/s. If coefficient of friction between surface and ball is 1/2​, then before stopping it will cover a distance of

Answer 1

We know that

v² = u² + 2as

putting

v = 0

u = 10 m/s

and a = −μg

on solving we will get

distance s = 10 m.
