(b) If the mass of M₁ = 525 g, what is the magnitude of the tension force in the cord
while in motion? (Hint: refer to your free body diagram in (a) and Fig. 5.1h.)
(c) Calculate the magnitude of the force exerted by the spring on mass M6 = 525 g,
moving in a circle of radius r = 21 cm, as shown in Fig. 5.1(a). The mass makes
19 revolutions in 17 seconds.
(d) Determine the mass m, suspended over the pulley shown in Fig. 5.1(b), which
stretches the spring by the same amount as during the rotation in (c).
