Question

Student Name:_Meg de longe 1. (20 pts) Simple Harmonic Oscillation a. The depression of a car when two people of total weight 150 kg get in the car is measured to be 2 cm. If the weight of the car is 900 kg what would be the frequency at which the car will bounce off the road after it hits a pothole. Assume that the shock absorber of the car is dead i.e., there is no damping? m= 1050 kg b. Describe what happens when the car hits a pothole after the shock absorber is fixed?

Answer 1

9.) Since we know that kre= ng k = 10 507 9181 0.02 k= 515025 H/4 lence J = 1 n h = 1 1 515025 515025 1050 f = 3.526 Hz b.) Absorber acts like damper and due to this damper amplitude of motion decreases with time.
