Question

If the mass of a sliding block is tripled while a constant net force is applied, by how much does the acceleration decrease?

Answer 1

As we know that if a rock is sliding under the influence of some external force then By Newton's II law we have

`F = ma`

now we will have

`a = (F)/(m)`

now we know that if force remains constant while we tripled the mass of the block then

new acceleration of the block will be given as

`a' = (F)/(3m)`

so here the acceleration of the block will be decreased by 3 times
