In the figure here, a solid brass ball of mass 0.298 g will roll smoothly along a loop-the-loop track when released from rest along the straight section. The circular loop has radius R = 0.19 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 = 7R, what is...
A small block of mass m slides along the frictionless loop the loop track shown below. If it starts from rest at point A, what is the speed of the block at point B? (v = squareroot (10 g R)) What is the net force acting on the block at point C? (Don't forget the gravitational force. (F = -mg (8i + j) At what height above the bottom should the block be released so that the normal force exerted...
In the figure, a small block of mass m = 0.022 kg can slide along the frictionless loop-the-loop, with loop radius R = 15 cm.

Consider a solid sphere of mass m and radius r being released from a height h (i.e., its center of mass is initially a height h above the ground). It rolls without slipping and passes through a vertical loop of radius R. a. Use energy conservation to determine the tangential and angular velocities of the sphere when it reaches the top of the loop. b. Draw a force diagram for the sphere at the top of the loop and write...
AP Physics C FRQ 3. A sphere of mass m and radius r is released from rest at the top of a curved track of height H. The sphere travels down the curved track and around a loop of radius R. The sphere rolls without slipping during the entire motion. Point A on the loop is at height R, and point B is at the top of the loop. The rotational inertia of the sphere is 2mr2/s. Express all of...
Problem 9 m,r A solid ball of mass m and radius r sits at rest at the top of a hill of height H leading to a circular loop-the loop. The center of mass of the ball will move in a circle of radius R if it goes around the loop. The moment of inertia of a solid ball is Ibull--mr. (a) Find an expression for the minimum height H for which the ball barely goes around the loop, staying...
