A 20 kg mass stretches a large spring 10 cm in equilibrium. It is attached to a dashpot that supplies a damping force of 800 N for each 2 m/sec of speed. The mass is initially displaced 1 m below equilibrium and given a downward velocity of 1 m/sec. Determine the type of damped motion and find its displacement in meters as a function y of time t. For simplicity, use g = 10 m/sec. This damped motion is Select an answer ✓ y(t) = meters

A mass weighing 64 pounds stretches a spring 0.32 foot. The mass is initially released from a point 8 inches above the equilibrium position with a downward veloc- ity of 5 ft/s. (a) Find the equation of motion.

An electron moves with a constant horizontal velocity of 3.0 x 100 m/s and no initial vertical velocity as it enters a deflector inside a TV tube. The electron strikes the screen after traveling 17.0 cm horizontally and 40.0 cm vertically upward with no horizontal acceleration. What is the constant vertical acceleration provided by the deflector? (The effects of gravity can be ignored.) 1.4 x 10 m/s? 14 2.5 x 10 m/s2 14 1.2 x 10 m/s? 8.3 x 10 m/s?
