A 4.1 g coin sliding to the right at 26.2 cm/s makes an elastic head-on collision with a 12.3 g coin that is initially at rest. After the collision, the 4.1 g coin moves to the left at 13.1 cm/s.
a) Find the final velocity of the other coin. Answer in units of cm/s
b) How much kinetic energy is transferred to the 12.3 g coin? Answer in units of J
