Answer:
C
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
