Question

Calculate the force required to accelerate a mass of 50kg to 10m/s2

Answer 1

Step-by-step explanation:

Basically force is given by the formula.

F= ma

Where m is mass of the body and 'a' is acceleration.

Here the time is not given, hence it is not possible to calculate acceleration, as acceleration is given by the formula

a= v/t

So most probably the question is wrong.

However if we take acceleration= 2m/s^2

Then F= ma= 50*2= 100N

However if the question was to find energy then it is sufficient to find kinetic energy as moving objects possess kinetic energy.kinetic energy is given by the formula:

KE= 1/2*m* v^2

I.e, KE= 1/2 * 50 * 2* 2

I.e, KE= 25*4= 100 J
