Problem statement
A force causes an acceleration of 10 m/s^2 in a body of mass 500 g. What acceleration would be caused by the same force in a body of mass 5 kg.
Solution
Case 1
mass = m=500 g = 0.5 kg
Acceleration = a =10 m/s^2
Force = ma = 0.5 . 10 = 5 N
This force value will be used as input parameter in the next case.
Case 2
Mass = m=5 kg
Force = F=5 N
And the acceleration = a (to be found out)
F = ma
=> a = F /m = 5/5 m/s^2 = 1 m/s^2
