which would required a great force - accelerating a 10g mass at 5m/s-2 or 20g mass at 2m/s-2 ?
Asked by Ajitesh jain | 20 Jul, 2010, 08:05: AM
Expert Answer
Force = MassxAcceleration
 
F1 = 10x5 = 50 N
F2 = 20x2 = 40 N
 
Thus, we will require more force to accelerate 10g mass at 5 m/s2 than 20g mass at 2 m/s2.
