Some curious students hold a rolling race by rolling four items down a steep hill. The four items are a solid homogeneous sphere, a thin spherical shell, a solid homogeneous cylinder and a hoop with all its mass concentrated on the hoop's perimeter. All of the objects have the same mass and start from rest. Assume that the objects roll without slipping and that air resistance and rolling resistance are negligible. For each statement below, select True or False. a)...
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...

Q10 A hollow sphere and a hoop of the same mass and radius are released at the same time at the top of an inclined plane. If both are uniform, (1) Which one reaches the bottom of the incline first if there is no slipping? (2) A uniform hollow sphere of mass 120 kg and radius 1.7 m starts from rest and rolls without slipping dow an inclined plane of vertical height 5.3 m. What is the translational speed of...

Two objects roll down a hill: a hoop and a solid cylinder. The hill has an elevation change of 1.4-m and each object has the same diameter (0.55-m) and mass. Calculate the velocity of each object at the bottom of the hill and rank them according to their speeds. [Hint: When an object is rolling, the angular speed and the velocity of the center of mass are related by ??cm = ??r, where ???? is the radius of the object.]...
Consider two cylindrical objects of the same mass and radius. Object A is a solid cylinder, whereas object B is a hollow cylinder.
Problem 3: Consider two cylindrical objects of the same mass and radius. Object A is a solid cylinder, whereas object B is a hollow cylinder.Part (a) If these objects roll without slipping down a ramp, which one will reach the bottom of the ramp first? Part (b) How fast, in meters per second, is object A moving at the end of the ramp if it's mass is 210 g, it's radius 14 cm, and the height of the beginning of the ramp is 13.5...

Please answer this two part question
A solid sphere of mass m and radius a rolls without slipping down a ramp that has a height h and is inclined at angle 0. The sphere is initially motionless. It takes 10 s for the sphere to roll to the bottom of the ramp. 2. a) Would a hoop of the same mass and radius take the same time, or more, or less? Explain. MR The hoop has a maller coeficient from...

A solid cylinder is released from the top of an inclined plane of height 0.682 m. From what height on the incline should a solid sphere of the same mass and radius be released to have the same speed as the cylinder at the bottom of the hill? Assume that both objects roll down the incline without slipping. m

A uniform, solid sphere of radius 5.00 cm and mass 4.75 kg starts with a purely translational speed of 1.75 m/s at the top of an inclined plane. The surface of the incline is 1.50 m long, and is tilted at an angle of 26.0∘ with respect to the horizontal. Assuming the sphere rolls without slipping down the incline, calculate the sphere's final translational speed ?2 at the bottom of the ramp. ?2=

A uniform, solid sphere of radius 4.00 cm and mass 2.25 kg starts with a purely translational speed of 2.25 m/s at the top of an inclined plane. The surface of the incline is 1.75 m long, and is tilted at an angle of 33.0∘ with respect to the horizontal. Assuming the sphere rolls without slipping down the incline, calculate the sphere's final translational speed ?2 at the bottom of the ramp.
