A child moving at constant velocity carries a 2 N ice cream cone 1 m across a level surface. Is she doing work? a. Yes, because the force acts perpendicular to the direction of motion c.

A Carnot engine, operating between hot and cold reservoirs whose temperatures are 800.0 and 400.0 K, respectively, performs a certain amount of work W1. The temperature of the cold reservoir is then lowered to 200.

What is the momentum of a 2 kg ball traveling at 2m/s
