Q1. The bullet penetrates into the block and stops due to its friction with the block. The compound system of the block plus the bullet rises to a height of 11 cm along a circular arc with a 20 cm radius A bullet with a m1 = 30.0 g mass is fired horizontally into a block of wood with m2 = 5.08 kg mass.

Q2. For a damped oscillator with a mass of 170g, the spring constant 140 N/m and a damping coefficient of 69.0 g/s, what is the ratio of amplitude of the damped oscillations to initial amplitude at the end of 27 cycles?
