A 100-kg man on ice skates pushes a 25-kg boy, also on skates, with a force of 250 N. As a result, A) both the man and the boy will have an acceleration of magnitude 2 m/s². B) only the boy will have an acceleration of magnitude 2 m/s². C) only the man will have an acceleration of magnitude 2 m/s². D) the boy will have an acceleration of magnitude 10 m/s². E) the heavier man will be stationary.

Question

Quizplus · Accepted Answer

The boy will have an acceleration of magnitude 10 m/s² because acceleration is calculated by dividing the force by the mass (a = F/m). For the boy, a = 250 N / 25 kg = 10 m/s².
