Q1. Bob, of mass m, drops from a tree limb at the same time that Esther, also of mass m, begins her descent down a frictionless slide. If they both start at the same height above the ground, which is true about their kinetic energies as they reach the ground?
Q2. A deuteron is accelerated from rest through a 10-kV potential difference and then moves perpendicularly to a uniform magnetic field with B = 1.7 T. What is the radius of resulting circular path? (Deuteron- m = 3.3 x 10-27 kg, q = 1.6 x 10-19 C)
