1,950 kg car

Four people enter a 1,950 kg car and discover that this compress the car's springs by an additional 0.70 cm. Together the people have a mass of
315 kg.
(a) If we pretend that the car's suspension consists of one spring, then we can calculate its effective spring constant, k. What is the value of k (in
N/m) for this car?
N/m
(b) The four people exit the car. They push down upon it once and then release it. This causes the car to undergo simple harmonic motion. What is
the frequency (in Hz) of this vibrating motion?
Hz
