Question C1
A 110 kg merry-go-round with radius of 0.85 m was accelerated from rest to 12 rad/s in 10 s when you applied a constant torque of 304
Nm on it. Right after it reached 12 rad/s, you immediately jumped on the edge of the merry-go-round platform which is 0.85 m away from
the axis of rotation.
By assuming the friction is the same before and after the jump, calculate
(a) the friction of the merry-go-round
(b) the angular velocity of the merry-go-round the moment you jumped on it. Assume you have a mass of 69.7 kg.
(c) the duration taken for the whole system to come to rest, from the moment you jumped on the merry-go-round.

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?
