Let's investigate the motion of a uniform cylinder (think of a checker piece rolling along its...
In this problem you will consider the motion of a cylinder ofradius that is rolled from a certain height so that it "loops the loop," that is, rolls around thetrack with a loop of radius shown in the figure without losing contact with thetrack. Unless otherwise stated, assume that friction is sufficient thatthe cylinder rolls without slipping. The radius of the cylinder is much smaller than the radius of the loop. Q. Compared to an object that does not roll,...
A cylinder of radius R=15.0cm and mass m=900g is released from rest at the top of an incline of height h=10.0m. It rolls, without slipping, to the bottom of the incline. Calculate cylinder's: a)moment of inertia about its center of rotation. b)angular velocity at the bottom of the incline.
A uniform cylinder of radius r15.0 cm and mass m 1.70 kg is rolling without slipping on a horizontal tabletop. The cylinder's center of mass is observed to have a speed of 4.60 m/s at a given instant. (a) What is the translational kinetic energy of the cylinder at that instant? J (b) What is the rotational kinetic energy of the cylinder around its center of mass at that instant? J (c) What is the total kinetic energy of the...
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...
2. A uniform, solid cylinder with mass M and radius 2R is on an incline plane with angle of inclination of 6. A string is attached by a yoke to a frictionless axle through the center of the cylinder so that the cylinder can rotate about the axle. The string runs over a disk-shaped pulley with mass M and radius R that is mounted on a frictionless axle through its center. A block of mass M is suspended from the...
A uniform, solid cylinder with mass 5 and radius 2*1.8 rests on a horizontal table. A string is attached by a yoke to a frictionless axle through the center of the cylinder such that the cylinder can rotate about the axle at the center. The string runs over a disk-shaped pulley with mass 5 and radius 1.8 that is mounted on a frictionless axle through its center. A block of mass 5 is suspended from the free end of the...
A solid, uniform eylinder, mass m and radius r starts from rest and rolls without slippng solid cylinder 7) down a track. Points A and B are on a circular part of the track having radius R. The diameter of the cylinder r R , so it doesn't need to be taken into consideration when calculating the potential energy U. a. What is the minimum height, ho for which the cylinder will make a complete loop-the loop without losing contact?...
4) Figures 4A (side view) and 4B (overhead view) illustrates a uniform solid cylinder having mass M and radius R. The cylinder is positioned on a horizontal floor having sufficient friction to ensure that the cylinder can roll without slipping. The cylinder includes a mass-less yoke that is fixed to the symmetric axis of the cylinder and acts as a rolling friction-less pivot for the cylinder. An ideal spring having spring constant K is attached to the yoke at one...
A uniform, solid cylinder with mass 3M and radius 2R rests on a horizontal tabletop. A string is attached by a yoke to a frictionless axle through the center of the cylinder so that the cylinder can rotate about the axle. The string runs over a disk-shaped pulley with mass M and radius R that is mounted on a frictionless axle through its center.

> he forgot about gravitational potential energy. It is not zero at the end because we are finding the speed so that it can pass the loop. The gravitational potential energy is equal to 2mgrloop putting this into the equation, the rights answer is going to be 2.75rloop
