Unformatted text preview: IVIidterm 2 1. (33 points) Two blocks of mass m and 2772. on an inclined planc with angle 0 from the horizontal are being held in place by a rope attached to the 1.01) bloc-has shown below. Assume that. there is no friction between the lower block and the inclined plane. W hat. is the minimum coefficient of static friction between the two blocks required 1.0 hold the blocks in place? mfizW sy%="“ S 75 : F6766 + '\ 7‘?‘ 7 2. (33 points) Two beads of mass m are attached to a. pivot by strings of length L as shown below. The system is set in motion with angular velocity u). There is no gravity. Find the tensions in both strings. Sy5= Icotfiom mags Sysfiiop we.“ 3. A ball of mass Ill, radius 1?, and moment of inertia £315” is initially sliding along a horizontal surface with speed m. The coefficient of kinetic friction between the ball and the ground is p. The friction causes the ball to start rotating. The questions below refer to the time during which the ball is both rolling and Sliding. (a) (10 points) Find the translational speed of the center of mass of the ball as a function of time. (b) (15 points) Find the rotational Speed of the ball about its center of mass as it function of time. (c) (8 points) Find the time it. takes for the hall to start rolling without sliding. ...
