The pulley in Fig. P9.75 has radius R and a moment of inertia I. The rope does not slip over the pulley, and the pulley spins on a frictionless axle. The coefficient of kinetic friction between block A and the tabletop is μk. The system is released from rest, and block B descends, Block A has mass mA and block B has mass mg. Use energy methods to calculate the speed of block B as a function of the distance d that it has descended.

- The mass of a hoop of radius 1.0 m is 6.0 kg. It rolls across a horizontal surface with a speed of 10.0 m/s. (a) How much work is required to stop the hoop? (b) If the hoop starts up a surface at 30 to the horizontal with a speed of 10.0 m/s, how far along the incline will it travel before stopping and rolling back down?arrow_forwardA small particle of mass m is pulled to the top of a friction less half-cylinder (of radius R) by a light cord that passes over the top of the cylinder as illustrated in Figure P7.15. (a) Assuming the particle moves at a constant speed, show that F = mg cos . Note: If the particle moves at constant speed, the component of its acceleration tangent to the cylinder must be zero at all times. (b) By directly integrating W=Fdr, find the work done in moving the particle at constant speed from the bottom to the top of the hall-cylinder. Figure P7.15arrow_forwardWhen the electricity goes out on your campus, a backup source powers the servers that handle communications and the Internet. Rather than use batteries, many installations use a flywheel, a heavy rotating disk that spins, very rapidly, with nearly zero friction. An electric motor spins up the flywheel, which continues to spin with very little energy input. When the system needs to provide power, the flywheel’s motion is used to turn an electric generator. A typical system has a 540 kg cylinder with a radius of 0.30 m. A small electric motor provides a constant 2.8 N ⋅ m torque to spin up the cylinder. If the cylinder starts at rest, how long does it take to reach its final spin rate of 13,000 rpm?arrow_forward
- The puck in the figure below has a mass of 0.120 kg. The distance of the puck from the center of rotation is originally 32.0 cm, and the puck is sliding with a speed of 80.0 cm/s. The string is pulled downward 12.5 cm through the hole in the frictionless table. Determine the work done on the puck. (Suggestion: Consider the change of kinetic energy.) 0 R m × Your response is off by a multiple of ten.

If the radius of the disk is r=400mm what is it's mass?.arrow_forwardThe L-shaped object in the figure(Figure 1) consists of three masses connected by light rods. Find the work that must be done on this object to accelerate it from rest to an angular speed of 2.00 rad/sr about the x axis. About the y axis. About the z axis (which is through the origin and perpendicular to the plane of the figure).arrow_forward
- D, In an electric vehicle, each wheel is powered by its own motor. The vehic le weight is 2,500kg. This vehicle increases its speed linearly from 0 to 70mph in 10seconds. The tire diameter is 75cm. Calculate the maximum power required from each motor in kW.arrow_forwardMalar is playing with a toy car track set and has made a vetical loop she wants to send a 150-gram car around. She has a hill for the car to roll down and if she releases it from a height of 24 cm above the top of the loop, which has a radius of 20 cm, it goes around the loop and exits with a speed of 3.12 m/s. How much energy was lost due to friction (between the car and the sides of the track, and the car's axels) during the entire trip? Hint: You don't have any details about the time while the car is going down the hill or through the loop, so you don't know how fast it is going at the top of the loop.arrow_forwardA block of 50 kg is attached to a cable. The cable is then attached to a rotating assembly with a mass moment of inertia of 10 kg-m^2. The bearing friction applied at the rotating assembly is equivalent to a couple of 50 N-m CCW. The block's initial downward speed is 1 m/s. 0.5 m 50 kg 1. Which of the following does negative work on the system? Bearing Friction Bearing friction AND weight Weight Neither bearing friction, nor weight. Both bearing friction and weight do positive work. 3.

The car with a mass of 210 kg including the passenger and the driver, starts from rest. The total tangential components of force on the car is EF, = 125 – 2.50D, where D is the distance the car travels along the track from the point where it starts. a.

A compressed spring shoots the block radially outward from the center along a frictionless groove in the surface of the turntable. Calculate the turntable's angular speed when the block reaches the outer edge. Treat the turntable as a solid disk with mass with mass 200 g and diameter 30.0 cm.
