- A disk spins at 4.0 revolutions/second. What is its period, in second? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.A hollow cylinder of mass M1 and radius R1 rolls without slipping on the inside surface of another hollow cylinder of mass M2 and radius R2. Assume R1<<RZ. Both axes are horizontal, and the larger cylinder is free to rotate about its axis What is the angular velocity or frequency of small oscillationsA cord connected at one end to a block which can slide on an inclined plane has its other end wrapped around a cylinder resting in a depression at the top of the plane as shown in ( Figure 1).

- NOTE: The answer of 85.715 rpm was given to me and was incorrect. What is the correct answer?A block of mass mA=20kg on an inclined plane and a bucket of mass mbucket=16kg are attached to the ends of a massless string passing through a massless pulley as shown in the figure below. The inclined plane makes an angle of θ=46o with the horizontal and the coefficients of kinetic and static friction are μk=0.21 and μs=0.58. The system is initially at rest and a student starts to fill the bucket with balls, each of whose mass is 100 grams, one at a time until the system starts to move. Determine the number of balls the student placed in the bucket. Take g=9.80m/s2 and please note that the number balls must be an integer!Two blocks, A and B, with masses of MA = 2M and MB = M, respectively, are connected together by a massless and non-elastic cord, as shown in the drawing. Block A lies on a table top, while block B hangs in the string one height, H above the floor. The massless pulley is stuck and thus can not achieve any translational movement, but it can rotate freely and frictionlessly about its own center. Assume that the pulley rotates so that the cord does not slide on the pulley. The system starts at rest before it is released. Assume that block A slides frictionlessly on the table top. Assume that the table top is long enough for block A to still be on the table when block B hits the floor. Show by means of energy conservation that the speed of the blocks as block B hits the floor is given by: v = squarerot 2gH / 3 question Explain briefly why the height of block A does not matter.
