Advanced Applied Mathematics - Circular Motion 1. When an airplane touches down at 1 = 0, a stationary wheel is subjected to a constant angu- lar acceleration a = 110 rad/s until / = 1 s. (a) What is the wheel's angular velocity at t = 1 s? (b) At 1 = 0, the angle 0 = 0. Determine 9 in radians and in revolutions at / = 1 s. 2. A small box B of mass mkg is placed on a rough horizontal rotating disc. B is metres from the centre of rotation as shown in Fig. 1 below. The coefficient of friction between the disc and B is u. Find, in terms of u, r and g, the maximum speed v that can be given to B without it slipping. 3. One end of a light inextensible string of length L metres is attached to a fixed point C.

The slider P in the image below has a constant velocity of 2.6 m/s to the left. Calculate the angular velocity w of link OA at the instant when 43° as shown, expressing your answer to one decimal place, in units of rad/s (but do not include the units in your answer). Use a sign convention that anticlockwise is positive (ie if you calculate 15.359 rad/s CW, your answer should be -15.4, and if CCW, 15.4). A 9cm 4cm P Ө 0
