Question

If I want to accelerate a mass of 3 kg at 5 m/s2 then how much force should I apply?

Answer 1

Answer: The force that must be applied is 15 N.

Step-by-step explanation:

Force exerted on the object is defined as the product of mass of the object and the acceleration of the object.

Mathematically,

`F=m* a`

where,

F = force exerted = ?

m = mass of the object = 3 kg

a = acceleration of the object =
`5m/s^2`

Putting values in above equation, we get:

`F=3kg* 5m/s^2=15N`

Hence, the force that must be applied is 15 N.
