2 A disc rotates with a constant angular acceleration of 0.46 rad/s“. At t = 0 s, the disc is rotating at -8.42 rad/s and a line segment from the center of the disc to the outer edge is at 0 = 0 rad. (a) Calculate how much time it takes for the disc to momentarily stop rotating after t = 0 s as it changes its direction of rotation. (b) How many times will the line segment pass 0 = 0 rad by the time it momentarily stops rotating after t = 0 s? (c) What is the angle of the line segment at that moment?

4. A pottery wheel of radius 20cm and mass M is freely rotating about an axis through its center at 87 rads/s. A blob of very dense clay of mass 5kg is gently placed on the spinning wheel halfway up its radius (i.e. 10cm from the axis of rotation). This causes the rate of rotation of the pottery wheel to drop to 7.8a rads/s. You can treat the pottery wheel as a uniform disk and the blob of clay as a point particle. The moment of inertia of a disk about an axis through its center is given by I = MR. (a) Write down expressions for the angular momentum of the system before and after the blob has been placed on the wheel. (b) Hence, find the mass M of the pottery wheel.
