The ﬁgure shows a 10 kg cart attached to a spring, and oscillating back and forth. At t = 0 s the spring is maximally compressed (5 cm shorter than normal) and the cart is stationary. At t = 1 s the spring is its equilibrium length, and at t = 2 s the cart is once again stationary because the spring is maximally extended (5 cm longer than normal). 3 (a) What is the frequency f of this oscillation? 5cm t=0s t=1s 3 (b) At t = 2...
