Q. You shoot a 58-g pebble straight up with a catapult whose spring constant is 310 N/m. The catapult is initially stretched by 0.20 m. How high above the starting point does the pebble fly? Ignore air resistance.
Q. For a damped oscillator with a mass of 160 g, a spring constant 80 N/m and a damping coefficient of 70 g/s, what is the ratio of the amplitude of the damped oscillations to the initial amplitude at the end of 22 cycles?
