Current Attempt in Progress In the figure here, a solid brass ball of mass 0.177 g will roll smoothly along a loop-the-loop track when released from rest along the straight section. The circular loop has radius R = 0.18 m, and the ball has radius r << R. (a) What is h if the ball is on the verge of leaving the track when it reaches the top of the loop? (b) If the ball is released at height h = 4R, what is the magnitude of the horizontal force component acting on the ball at point Q? h (a) h= i (b) F= i Q 4

A pendulum consists of a rod of length 2 m and mass 3 kg with a solid sphere of mass 1 kg and radius 0.3 m attached at one end. The axis of rotation is as shown below. What is the angular velocity of the pendulum at its lowest point if it is released from rest at an angle of 30 ?
A pendulum consists of a rod of mass 2 kg and length 1 m with a solid sphere at one end with mass 0.3 kg and radius 20 cm (see the following figure). If the pendulum is released from rest at an angle of 30 , what is the angular velocity at the lowest point?
Consider two cylinders that start down identical inclines from rest except that one is frictionless. Thus one cylinder rolls without slipping, while the other slides frictionlessly without rolling. They both travel a sh01t distance at the bottom and then start up another incline. (a) Show that they both reach the same height on the other incline, and that this height is equal to their original height. (b) Find the ratio of the time the rolling cylinder takes to reach the height on the second incline to the time the sliding cylinder takes to reach the height on the second incline. (c) Explain why the time for the rolling motion is greater than that for the sliding motion.
Small bodies of mass m1 and m2 are attached to opposite ends of a thin rigid rod of length L and M. The rod is mounted so that it is free to rotate in a horizontal plane around a vertical axis (see below). What distance d from m1 should the rotational axis be so that minimum amount of work is required to set the rod rotating at an angular velocity ?
A uniform rod of mass 1.0 kg and length 2.0 m is free to rotate about one end (see the following figure). If the rod is released from rest at an angle of 60 with respect to the horizontal, what is the speed of the tip of the rod as it passes the horizontal position?
Integrated Concepts Riders in an amusement park ride shaped like a Viking ship hung from a large pivot are rotated back and forth like a rigid pendulum. Sometime near the middle of the ride, the ship is momentarily motionless at the top of its circular arc. The ship then swings down under the influence of gravity. (a) Assuming negligible friction, find the speed of the riders at the bottom of its arc, given the system's center of mass travels in an arc having a radius of 14.0 m and the riders are near the center of mass. (b) What is the centripetal acceleration at the bottom of the arc? (c) Draw a free body diagram of the forces acting on a rider at the bottom of the arc. (d) Find the force exerted by the ride on a 60.0 kg rider and compare it to her weight. (e) Discuss whether the answer seems reasonable.
A cord is wrapped around the rim of a solid cylinder of radius 0.25 m, and a constant force of 40 N is exerted on the cord shown, as shown in the following figure. The cylinder is mounted on frictionless bearings, and its moment of inertia is 6.0kgm2 . (a) Use the work energy theorem to calculate the angular velocity of the cylinder after 5.0 m of cord have been removed. (b) If the 40-N force is replaced by a 40-N weight, what is the angular velocity of the cylinder after 5.0 m of cord have unwound?
Describe how work is done by a skater pulling in her arms during a spin. In particular, identify the force she exerts on each arm to pull it in and the distance each moves, noting that a component of the force is in the direction moved. Why is angular momentum not increased by this action?
A solid sphere is released from height h from the top of an incline making an angle θwith the horizontal. Calculate the speed of the sphere when it reaches the bottom ofthe incline (a) in the case that it rolls without slipping and (b) in the case that it slidesfrictionlessly without rolling. (c) Compare the time intervals required to reach thebottom in cases (a) and (b).
Hi, I am in phyics I and they ask they show the angular position of a potter's wheel. If I know the angular displacement of 13 rad and the velocity of w=-2.5s, how do I find what is the maximum speed of a point on the outside of the wheel 15 cm from the axle? Please include detailed steps so I can understand. Thank you
A 4.6kg block resting on a smooth horizontal surface is attached to a string that passes over a frictionless pulley. The pulley has a radius of .48 m. a force of 8.5N pulls the other end of the string. As a result, the block moves a distance of .35m starting from rest. Find the (a) acceleration of the block, (b) angular acceleration of the pulley and (c) moment of inertia of pulley. Show complete solutions. plsssss help me answer this question, thank you.
