Question

According to Newton's second law of motion how much force will be required to accelerate an object at the same rate if it's mass is reduced by half?

A - four times the amount of force is needed
B - half the amount of force will be required
C- no change
D - twice the amount of force will be required

Answer 1

The answer will be B

Answer 2

F=ma.  So if a is to remain the same and m is halved, then F is halved also.  B is the answer.
