Question

Calculate force required to push of object of mass 50 kg with acceleration 2 m/s²​

Answer 1

Explanation:

Given,

Mass = 50 kg

Acceleration = 2 m/s²

Force = Mass * Acceleration

= 50 * 2

= 100 kgm/s²

= 100 N Ans.

Ans.) 100 N force will

Answer 2

Answer:

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
