Problem
Two ice skaters stand on frictionless ice facing each other. Skater A has mass 50kg and Skater B has mass 40kg. Skater A pushes Skater B with a constant horizontal force FA→B=20^−15^N for 0.50s.
(i) Write the force exerted by Skater B on Skater A.
(ii) Calculate the acceleration vector of each skater while the push lasts.
(iii) Assuming both skaters were at rest before the push and the force remains constant for 0.50s, determine the velocity vector of each skater immediately after the push ends.
