A force accelerates a body of mass M.A second body requires twice as much force to produce the same acceleration.What is the mass of the second body?
A)M
B)2M
C)M/2
D)4M
E)M/4

Question

Quizplus · Accepted Answer

The force required to accelerate an object is directly proportional to its mass (F = ma). If the second body requires twice as much force for the same acceleration, its mass must be twice as much, hence 2M.
