A shock absorber spring on a heavy duty truck is 21V,feet long. When installed, the spring compresses to 2 feet. The truck weighs 7 200 1bs, so each shock absorber has a load of 1,800 lbs. Treat the compression of the spring the same as if 1,800 lbs would stretch it by 6 inches.) a What is the spring constant? b) What is the coefficient of resistance that would cause the spring to be critically damped? 4.A simple pendulum of length 3 feet long is given an initial angular velocity of 15'/sec away from the vertical from the position of 5 a Find the equation of motion b) What is the amplitude? c What is the period of the pendulum? d) What is the angular velocity as it crosses the vertical (equilibrium) position?
