A70-kilogram hockey player skating east on an
ice rink is hit by a 0.1-kilogram hockey puck
moving toward the west. the puck exerts a
50-newton force toward the west on the player.
determine the magnitude of the force that the
player exerts on the puck during this collision.

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c
