A system consists of a disk rotating on a frictionless axle and a piece of clay moving toward it, as shown in the figure above. The outside edge of the disk is moving at a linear speed v, and the clay is moving at speed v/2. ANSWER= It is the same because there is no external torque acting on the system, A What is the magnitude of the angular momentum at time t=2s? ANSWER= 12kg*m^2/s, B Block 1, with mass m, moves towards Block 2, with mass 2m, on a straight horizontal track, as shown in Figure 1. Friction between the blocks and track is negligible.ANSWER= Small Arrow to the left, B Two objects are released from rest at the top of ramps with the same dimensions, as shown in the figure above. The sphere rolls down one ramp without slipping.?ANSWER= The block, because it does not gain rotational kinetic energy, but the sphere does, D Two objects, A and B, each experience a net external torque that varies over an interval of 5 seconds.Object B has a rotational inertia that is twice that of Object A. ANSWER= Torque B is 2 times Torque A, B A horizontal platform is initially rotating about a vertical axis as shown in Figure 1. A stationary disk is dropped directly onto the center of the platform..ANSWER= It decreases. The top disk exerts a torque on the platform, A A disk rolls without slipping down an incline as shown in Figure 1. A force diagram, which represents the forces exerted on the disk and the locations at which the forces are exerted, is shown in Figure 2. ANSWER= Gravity Only, A The wheel on a vehicle has a rotational inertia of 2.0 kg "m2. At the instant the wheel has a counterclockwise angular velocity of 6.0 rad/s, an average counterclockwise torque of 5.0 N -m is applied and continues for 4.0 s. ANSWER= 20 kg/m^2, C A block slides down an inclined plane whose roughness varies, but whose incline is constant. The graph shows the block's velocity as a function of time.ANSWER= E2=E4=0, D A satellite in circular orbit around Earth is initially not rotating with respect to its center of mass. Two identical thrusters on opposite sides of the satellite fire in opposite directions over the same 10-minute time interval, as shown above, and then turn off. ANSWER= Increases, No effect, C The diagram above shows a top view of a child of mass M on a circular platform of mass 5M that is rotating counterclockwise. Assume the platform rotates without friction. ANSWER= None of the actions described with change the total angular momentum of the child-platform system, D A sphere of mass m and radius r rolls without slipping down a ramp that makes an angle 0 with the horizontal, as shown. ANSWER= A/R, A At time t = 0s, a solid disk of radius 0.5 m rolls without slipping across a floor with a constant translational velocity of v = 4.5 m/s.ANSWER= 9 rad/sec, D A ball is launched from the ground with an initial velocity of 8.0 m/s at an angle of 60° above the horizontal. ANSWER= 2.4m, C Planet X has a radius R and mass M. Planet Y has a radius 2R and mass 2M. ANSWER= 2, C Made with nCreator - tiplanet.org
