Q. A ball dropped from a height of 4.00 m makes an elastic collision with the ground. Assuming no mechanical energy is lost due to air resistance, a) show that the ensuing motion is periodic, b) determine the period of the motion.

Q. A simple harmonic oscillator consists of a block mass 2.00 kg attached to a spring of spring constant 100 N/m. When t=1.00 s, the position and velocity of the block are x= 0.129 m and v = 3.415 m/s .

What was the velocity of the block at time t=0 s?
