... 4) A ball is oscillating on an ideal spring with an amplitude of 8.3 cm and a period of 4.6 s. Write an expression for its position, x, as a function of time t, if x is equal to 8.3 cm at t = 0.0 s. Use the cosine function. Answer: x = (8.3 cm) cos[2πt/(4.6 s)] or x = (8.3 cm) cos[(1.4 s-1)t] 5) An ...

Both this and that of disk C cause the tension T2 = 49 N, which allows us to conclude that disk C has a mass of 4.0 kg. The weights of these two disks plus that of disk B determine the tension T1 = 58.8 N, which leads t ...
