A solid ball of mass 2.0 kg rolls down a hill of slope 38 degree without slipping. Find the acceleration of the ball’s center of mass, the frictional force between ball and ground, and the minimum coefficient of static friction needed to prevent slipping.
A 1.9 m radius cylinder with a mass of 531.1 kg rolls without slipping down a hill which is 56.5 meters high. At the bottom of the hill, what fraction of its total kinetic energy is invested in rotational kinetic energy?
A 1.2 m radius cylinder with a mass of 8.8 kg rolls without slipping down a hill which is 5.7 meters high. At the bottom of the hill, what percentage of its total kinetic energy is invested in rotational kinetic energy?
A 1.2 m radius cylinder with a mass of 5.9 kg rolls without slipping down a hill which is 8.2 meters high. At the bottom of the hill, what fraction of its total kinetic energy is invested in rotational kinetic energy?
1) A solid ball of mass M and radius R rolls without slipping down a hill with slope tan θ. (That is θ is the angle of the hill relative to the horizontal direction.) What is the static frictional force acting on it? It is possible to solve this question in a fairly simple way using two ingredients: a) As derived in the worksheet when an object of moment of inertia I, mass M and radius R starts at rest...
A thin spherical shell of radius 1.32 meters rolls down a 8.25 meter high hill without slipping. At the bottom of this hill, what will the velocity of the spherical shell be?
2. Rolling down the hill (a) A solid cylinder of mass 1.0 kg and radius 10 cm starts from rest and rolls without slipping down a 1.0 m-high inclined plane. What is the speed of the cylinder when it reaches the bottom of the inclined plane? (b) How about a solid sphere of the same mass and radius? (c) How about a hoop of the same mass and radius? (d) Which of the above objects is moving fastest when it...
A solid ball with m=1.6 kg and radius 3.8 cm rolls a distance 9.2 m down a ramp that is inclined by an angle 22.2° with respect to the horizontal. At the bottom of the ramp, what is its rotational kinetic energy? The answer is 15.59 J but i'm unsure how to arrive at this.
A ball of mass m = 2 kg and radius r = 0.2 meters, rolls down a water slide, like shown. The slide curves up at the end and launches the ball into the air. The height is h = 1.5 meters, angle ? = 60°, and the angle ? = 25°. If the ball starts at rest, and rolls without slipping, find ymax, the height to which the child is launched, in meters. Treat the ball as being launched...
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...
