A thin hoop of radius 2.00 cm and mass 0.0300 kg rolls down a frictionless ramp of length 4.00 m that makes an angle of 10.0° with the horizontal. The hoop starts from rest from the top of the ramp.a. Find the angular speed of the hoop at the bottom of the ramp.b. After the hoop rolls off the ramp, it is traveling along a horizontal surface with friction that causes a frictional torque of magnitude 0.400 N·m on the hoop. How much time will it take for the hoop to come to rest?

I need some help. Can you walk me through how to solve this problem? To throw the discus, the thrower holds it with a fully outstretched arm. Starting from rest, he begins to turn with a constant angular acceleration, releasing the discus after making one complete revolution. The diameter of the circle in which the discus moves is about 1.9 m. If the thrower takes 1.2 s to complete one revolution, starting from rest, what will be the speed of the discus at release?
A 25-kg child stands at a distance of 1 m from the axis of a rotating merry-go-round. The merry-go-round can be approximated as a uniform solid disk with a mass of 500 kg and a radius of 2.0 m. The top rods and central axis are neglected. Find the moment of inertia of this system in kg.m². Round to the nearest integer. Take g to be 10 m/s². Attach your work for partial credit. 2 m 1m
In the rotational motion experiment, a student wanted to measure the moment of inertia I of a disc, If he found out that the torque acting on the disc to be 2.7 N.m and the angular acceleration to be 21.01 rad/s?, find the moment of inertia ( in units of kg. m²) of the disc.

For each question, use degrees NOT radians. Healthcare professionals, when measuring range of motion (ROM) and isokinetic strength, use degrees - so this assignment will use answers in degrees as well. A person is laying on their stomach doing a hamstring curl. They go from fully extended (0o) to 130o of flexion. What is their angular displacement if the person is on their stomach with their head facing left (feet pointing right)?
