Question

A 50gk boy on a rough horizontal ground the coefficeint of static friction is 0.68

Answer 1

Given that,

Mass of a boy = 50 kg

The coefficient of static friction = 0.68

To find,

Let us assume we need to find the maximum static friction between the boy and the ground.

Solution,

The formula for the maximum static friction between the two objects is given by :

$F=\mu N$

Where

N is normal force

Substitute all the values,

$F=0.68\times 50\times 10\\\\F=340\ N$

Therefore, the maximum static friction between the boy and the ground is 340 N.
