A solid cylinder of radius R and mass m, and moment of inertia mR2/2, starts from rest and rolls down a hill without slipping.
A solid cylinder of radius R and mass m, and moment of inertia mR2/2, starts from rest and rolls down a hill without slipping. At the bottom of the hill, the speed of the center of mass is 4.7 m/sec. A hollow cylinder (moment of inertia mR2) with the same mass and same radius also rolls down the same hill starting from rest. What is the speed of the center of mass of the hollow cylinder at the bottom of...

1. A solid sphere of radius R, mass M. and mo- ment of Inertia I = MR is rolling down a hill. It starts at rest at a height h. Find its speed at the bottom of the hill. Compare this to the speed an object of mass M would have after sliding down a frictionless hill also of height h.

A non-uniform cylinder with mass M and radius R rolls without sliding across the floor. If it's mass was 2 kg and its radius 32 cm, and it was rolling at an angular speed of 13 rad/sec, how far up a hill can the cylinder roll without slipping?

3. A car with mass m travels over a hill with a radius of curvature of r at a speed of 15 m/s. What is the normal force on the car when the car is at the top of the hill? (6 pts) the car has a mass of 1200 Kilograms and the radius of curvature is 25 meters 4. A student with a mass of m rides a roller coaster with a loop with a radius of curvature of...

3. A frictionless roller-coaster goes around a circular loop of radius 11 m. It enters the bottom of the loop going 32 m/s. Find the speed of the roller-coaster when it gets to the top of the loop 4. For the loop in the previous problem find the velocity of the roller-coaster as a function of height off the ground. Use that to find the centripetal acceleration as a function of height. Plot the centripetal acceleration as a function of...
A string is wrapped around a uniform disk of mass M = 2.2 kg and radius R = 0.1 m. (Recall that the moment of inertia of a uniform disk is (1/2) MR2.)
A string is wrapped around a uniform disk of mass M = 2.2 kg and radius R = 0.1 m. (Recall that the moment of inertia of a uniform disk is (1/2) MR2.) Attached to the disk are four low-mass rods of radius b = 0.13 m, each with a small mass m = 0.7 kg at the end. The device is initially at rest on a nearly frictionless surface. Then you pull the string with a constant force F...

A cylinder with moment of inertia I about its center of mass, mass
m, and radius r has a string wrapped around it which is tied to the
ceiling (Figure 1) . The cylinder's vertical position as a function
of time is y(t).At time t=0 the cylinder is released from rest at a height h above
the ground.Part

The moment of inertia of a cylinder of mass m, radius a, length l, about its axis is given by 3ma2/5. This cylinder is rolling with speed V on a rough horizontal plane and the coefficient of friction between the cylinder and the plane is u. A constant braking couple of magnitude 11umag/5 is applied to the cylinder at time t= 0 and is maintained. Show that the cylinder skids immediately. Show also that the cylinder will instantaneously cease to...

Problem 1: Looping. The looping of a roller coaster has the radius R. The roller coaster starts at rest in height H over the deepest point of the looping (as shown in the figure). Neglect friction and consider the roller coaster as a mass point of mass m. Q.1) Express the total energy of the body. The reference point for the potential energy is at the center of the loop. Q.2) Find the speed of the body at the top...

A non-uniform density cylinder has a radius R=6m. The rotational inertia of this cylinder can be taken to be I=βMR2, where β is unknown and M is the mass of the cylinder. The cylinder is initially rotating with angular velocity ω0= 1.00rad/s, and is placed on a rough horizontal surface. The speed of the center of mass (CM) of the cylinder, as it is placed on the surface, is 0. The cylinder at first rolls and slips. Just as it...
