Question

If the mass of a

sliding block is tripled while a constant netforce is applied, by
how much does the accelerationdecrease?

Answer 1

The final acceleration becomes (1/3) of the initial acceleration.

Step-by-step explanation:

The second law of motion gives the relationship between the net force, mass and the acceleration of an object. It is given by :

`F=ma`

m = mass

a = acceleration

According to given condition, if the mass of a sliding block is tripled while a constant net force is applied. We need to find how much does the acceleration decrease.

`a=(F)/(m)`

Let a' is the final acceleration,

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

m' = 3m

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

`a'=(1)/(3)* (F)/(m)`

`a'=(1)/(3)* a`

So, the final acceleration becomes (1/3) of the initial acceleration. Hence, this is the required solution.
