A 10-N block and a 1-N block lie on a horizontal frictionless table. To impart equal horizontal accelerations, we would have to push the heavier block with
A)an equal force.
B)10 times as much force.
C)10 squared or 100 times as much force.
D)1/10 as much force.
E)none of the above

According to Newton's second law, force is equal to mass times acceleration (F=ma). To impart the same acceleration to both blocks, the force applied must be proportional to their masses. Since the heavier block is 10 times heavier, it requires 10 times as much force to achieve the same acceleration.
