The car has a mass of 1500 kg (kilograms) and the combined effect of the springs in the suspension system is that of a spring constant of 4000 N/m (.e.each of the four springs has a spring constant of 1000 N/m). Before a damping mechanism is installed in the car, when the car hits a bump it will bounce up and down. How may bounces will a rider experience in the minute right after the car hits a bump? Alternatively, what is the frequency in cycles per minute The car will bounce 15.9939 times per minute Your job is to design a damping mechanism which eliminates oscllations when the car hits a bump. What is the minimum value of the effective damping constant that can be used? Y48989 ✓ kg/sec Suppose that at time t=0 the car hits a bump. Immediately before that time the car was not moving up and down and the effect of the bump is to add a vertical component to the speed of the car of 10 meter/sec. How high will the car rise above its equilibrium position if you design the system with the damping constant you found in part (b)? It will rise 0,5553x meters above the equilibrium position. 7.

Assume that there is no water resistance. A weight of 100 kilograms of negligible volume is attached to the bottom of the log so that it remains vertical (so the total mass of the log and weight together is 200 kilograms). The mass density of water is 1000 kilograms per cubic meter. (For convenience, assume that the acceleration due to gravity is g=10 meters per sec)
