4. Bugs Bunny and Daffy Duck are on a merry-go-round which is accelerated uniformly from rest. Bugs jumps off and increases the speed so that the ride attains an angular speed of 10.2 rad/s in the first 18 seconds. If the net applied torque is 1400 N m, what is the moment of inertia of the merry-go-round?

A certain merry go round is accelerated uniformly from rest and attains an angular speed of 1.2 rad/s in the first 18 seconds. Also given (if needed): Net applied torque is 1200 Nm Moment of inertia is 18181 kg•m^2 Kinetic Energy is 13090 J Assuming friction is negligible, how much work does the motor have to do to accelerate the merry go round up to 1.2 rad/s? How much power does the motor have to generate to accelerate the merry...

Starting at rest, a child applies a 63N force tangent to the
edge of a merry-go-round through 31 2 rotations. At that moment,
she stops and admires her spinning merry-go-round. Then she jumps
onto the edge of the merry-go-round. The girl’s mass is 25kg, the
merry-go-round’s moment of inertia is 70kg· m2, and the
merrygo-round’s diameter is 2.0m. What is the final angular speed of
the girl and merry-go-round?

(4) A playground ride, known as merry-go-round, consists of a disk with a mass of 40.0 kg and a radius of 1.80 m mounted on a frictionless axle. The frictionless axle is a vertical cylinder of radius kg, and has the same rotational axis as the disk. A child with a mass of 3.50 m/s on a line tangential to the outer rim of the disk and jumps onto the outer edge of the ride while it is at rest...
