Two people with a combined mass of 120kg hop into an old car with worn-out shock absorbers. This causes the springs to compress by 8.30 cm. When the car hits a bump in the road, it oscillates up and down with a period of 1.70s.
A 2.16 kg block on a horizontal floor is attached to a horizontal spring that is initially compressed 0.0320 m. The spring has force constant 840 N/m.
