6. The shock absorbers of an old car with a mass of 1300 kg are worn. When a 680 N person slowly climbs into the car at its center of gravity, the car drops 5.0 cm. When the car, with the person on board, falls into a hole, it begins to oscillate vertically in a simple harmonic movement. Consider the car and the person as one body (only one mass) in a single spring and calculate (a) the period and (b) the oscillation frequency
we can find the spring constant
F = kx
k = F / x
here F is weight of the person
k = 680 / 0.05
k = 13600 N/m
--------------------------------------------
the time period is given as
T = 2 * sqrt ( m / k)
here m = ( 680 / 9.8) + 1300 = 1369.38 kg
so,
T = 2 * sqrt ( 1369.38 /
13600)
T = 1.993 sec
------------------------------------------
frequency , f = 1 /T
f = 0.5015 Hz
6. The shock absorbers of an old car with a mass of 1300 kg are worn....
Two people with a combined mass of 139 kg hop into an old car with worn-out shock absorbers. This causes the springs to compress by 9.20 cm . When the car hits a bump in the road, it oscillates up and down with a period of 1.73 s . A) Find the total load supported by the springs. B) Find the mass of the car.
Two people with a combined mass of 128 kg hop into an old car with worn-out shock absorbers. This causes the springs to compress by 9.80 cm . When the car hits a bump in the road, it oscillates up and down with a period of 1.74 s . Part A Find the total load supported by the springs. Part B Find the mass of the car.
How do I solve this?
A car has a mass of 1405 kg, and its shock absorbers have a spring constant of 30900 N/m. When it hits a bump, what is its period of oscillation? (Unit -s) 003-20g Acellsa Corponation. All Rights Reserved
1-/7 points 1.

1. Suppose that a car weighing 4000 pounds is supported by four shock absorbers Each shock absorber has a spring constant of 6500 lbs/foot, so the effective spring constant for the system of 4 shock absorbers is 26000 lbs/foot.1. Assume no damping and determine the period of oscillation of the vertical motion of the car. Hint: g= 32 ft/sec22. After 10 seconds the car body is 1 foot above its equilibrium position and at the high point in its cycle....
