Question

A 32.5-kg rock is traveling at a constant velocity through space. Then a force of 140 N is exerted on the rock. What acceleration does the force produce?

3.31 m/s^2
2.32m/s^2
4.31 m/s^2
45.5 m/s^2
10.7 m/s^2

Answer 1

As per Newton's II law we can say force applied on an object is product of mass and acceleration

`F = ma`

given that

Force = 140 N

mass = 32.5 kg

now we can use above formula

`140 = 32.5* a`

`a = (140)/(32.5)`

`a = 4.31 m/s^2`

so its acceleration must be 4.31 m/s^2
