Question

Two skaters,a man and a woman, are standing on ice. Neglect any friction between the skate blades and the ice. The woman pushes on the man with a certain force that is parallel to the ground. (a) Must the man accelerate under the action of this force? If so, what three factors determine the magnitude and direction of his acceleration? (b) Is there a corresponding force exerted on the woman? If so, where does it originate? Is this force related to the magnitude and direction of the force the woman exerts on the man? If so, how?

Explanation / Answer

Let the mass of man = M Let the mass of woman = m Let the force on them = F a) The acceleration of man, aman = F/M b) The acceleration of woman, awoman = F/W
