Question
What would be the force required to produce an acceleration of 2 m/s2 on a body of mass 12 kg? What would be its acceleration if the force was doubled?
Solution
Case I:
Acceleration, a = 2 m/s2
Mass of the body, m = 12 kg
Therefore,
Force , F = ma = 12 x 2 = 24 N.
Case 2:
Mas of the body, m = 12 kg
When force is doubled on the body,
Force acting, F = 48 N
Therefore,
Acceleration, a = F/m = 48/12 = 4m/s2
