Chapter 3, Problem 10RQ

To determine

The increase in acceleration of a sliding block when net force acting on it is tripled.

Answer to Problem 10RQ

The acceleration of a sliding block is tripled when net force acting on it is tripled.

Explanation of Solution

Write the expression of Newton’s second law.

$F=ma$

Here,

F is the net force acting on sliding block

m is the mass of sliding block

a is the acceleration of sliding block

In the above expression of Newton’s second law, the net force acting on a sliding block is directly proportional to the acceleration of the sliding block. When the total force exerting on the sliding block is tripled, then an acceleration of the block will also get tripled.

Conclusion:

Therefore, the acceleration of a sliding block is tripled when net force acting on it is tripled.
