A)just as much force.
B)10 times as much force.
C)100 times as much force.
D)one-tenth the amount of force.
E)none of these

According to Newton's Second Law of Motion (F=ma), the force required to accelerate an object is directly proportional to its mass. Therefore, to accelerate a 10-kg brick with the same acceleration as a 1-kg brick, one would need to apply 10 times the force.

A Push on a 1-Kg Brick Accelerates It
