Q1. The deuterium nucleus starts out with a kinetic energy of 6.2e-14 joules, and proton starts out with a kinetic energy of 1.23e-13 joules. The radius of a proton is 0.9e-15 m; assume that if the particles touch, distance between their centers will be twice that. What will be the total kinetic energy of both particles an instant before they touch?
Q2. A lead ball is dropped into a lake from a diving board 5 above the water. After entering the water, it sinks to the bottom with the constant velocity equal to the velocity with which it hit the water. The ball reaches the bottom 3.20 after it is free.
