Quizplus · Accepted Answer

According to Newton's second law, F = ma, where F is the force applied, m is the mass of the object, and a is the acceleration produced. Thus, to produce the same acceleration in a 10-kg brick, the force needs to be 10 times as much as that required for the 1-kg brick because the mass is 10 times greater. Therefore, the correct answer is B.

A Push on a 1-Kg Brick Accelerates the Brick
