The flywheel of a steam engine runs with a constant angular speed of 156 rev/min. When steam is shut off, the friction of the bearings and of the air brings the wheel to rest in 2.20 h. (a) What is the constant angular acceleration of the wheel, in rev/min2? (b) How many rotations will the wheel make before coming to rest? (c) What is the tangential linear acceleration
of a particle 52.4 cm from the axis of rotation when the flywheel is turning at 72.5 rev/min? (d) What is the magnitude of the total linear acceleration of the particle in part (c)?

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.

An object of mass m = 0.25 kg oscillates in a fluid at the end of a vertical spring of spring
constant kH = 85 N/m, see Fig.1. The effect of the fluid resistance is governed by the
damping constant b = 0.07kg/s.
(i) Find the period of the damped oscillation.
(ii) By what percentage does the amplitude of the oscillation decrease in each cycle?
