Q1. Tony (of mass 55 kg) coasts on his bicycle (of mass 20 kg) at a constant speed of 4 m/s, carrying a 12 kg pack. Tony throws his pack forward, in the way of his motion, at 3 m/s relative to the speed of bicycle just before the throw.

What is momentum of the system immediately after the pack is thrown?

reply in units of kg • m/s

Q2. A 18.0cm x 18.0cm square loop of wire lies in the xy-plane with its bottom edge on the x-axis. The resistance of the loop is 0.470. A magnetic field B parallel to the z-axis is given by 0.810*t*y^2, where B is in tesla, y in meters, and t in seconds. What is the size of an induced current in the loop at = 0.540?
