Suppose a boy is enjoying a ride on a merry-go-round which is movingwith a constant speed of 10 m s –1. It implies that the boy is(a) at rest(b) moving with no acceleration(c) in accelerated motion(d) moving with uniform velocity

Suppose a boy is moving with a uniform velocity of 10 m/s on a merry-go-round ride. Which of thefollowing is true of the given scenario?a. The boy is at restb. The boy is moving with no accelerationc. The boy is moving with accelerated motiond. The boy is moving with uniform velocity

A merry-go-round is a playground ride that consists of a large disk mounted to that it can freely rotate in a horizontal plane. The merry-go-round shown is initially at rest, has a radius R = 1.3 meters, and a mass M = 226 kg. A small boy of mass m = 47 kg runs tangentially to the merry-go-round at a speed of v = 2.1 m/s, and jumps on. Part (a) Calculate the moment of inertia of the merry-go-round, in kg ⋅ m2. Part (b) Immediately before the boy jumps on the merry go round, calculate his angular speed (in radians/second) about the central axis of the merry-go-round. Part (c) Immediately after the boy jumps on the merry go round, calculate the angular speed in radians/second of the merry-go-round and boy. Part (d) The boy then crawls towards the center of the merry-go-round along a radius. What is the angular speed in radians/second of the merry-go-round when the boy is half way between the edge and the center of the merry go round? Part (e) The boy then crawls to the center of the merry-go-round. What is the angular speed in radians/second of the merry-go-round when the boy is at the center of the merry go round? Part (f) Finally, the boy decides that he has had enough fun. He decides to crawl to the outer edge of the merry-go-round and jump off. Somehow, he manages to jump in such a way that he hits the ground with zero velocity with respect to the ground. What is the angular speed in radians/second of the merry-go-round after the boy jumps off?

A girl and a boy are riding on a merry-go-round that is turning at a constant rate. The girl is near the outer edge, and the boy is closer to the center. Who has greater linear speed?Group of answer choicesBoth the girl and the boy have the same nonzero linear speed.The girl has greater linear speed.Both the girl and the boy have zero linear speed.The boy has greater linear speed.

A Merry Go Round (MGR) has a radius of 18 meters. At t = 0, the Merry Go Round (MGR) has an angular velocity of 1.2 radians/second. The MGR also has a constant angular acceleration. After 3 seconds have elapsed, MGR has an angular velocity of 2.5 radians/second. A RIDER IS STANDING AT THE OUTER EDGE OF THE MGR.(a) What is the angular acceleration of the MGR? 0.433 radians/s^2(b) What is the tangential acceleration of the MGR? m/s^2(c) What is the tangential velocity of the RIDER after 3 s?

A child is riding a merry-go-round which completes one revolution every 8.36 s.The child is standing 4.65 m from the center of the merry-go-round.What is the tangential speed of the child?Express your answer in m/s.
