Problem 90

Background and context

The mass of the sand added to the bucket. 

Solution:

The mass of the sand added =10.6 kg.

Explanation:

Given:

Mass of the block,   

Mass of the bucket,   

Coefficient of static friction between the table and block is 0.45.

Coefficient of kinetic friction between the table and block is 0.32.

Formula used:

From Newton’s second law of motion:

Where, m is the mass and a is the acceleration.
