Question

5. In a Circus, a motor-cyclist having mass of 50 kg moves in a
spherical cage of radius 3 m. Calculate the least velocity with
which he must pass the highest point without losing contact.
Also calculate his angular speed at the highest point.​

Answer 1

Answer:

force acting on motorcyclist=mg+n

when motorcyclist just lose contact. N=0

m.v²/r=mg

m gets cancelled on both sides

v²=rg

v=√rg

v=√3×9.8

v=5.421

w=v/r

w=5.421/3

w=1.807 rad/s

Thus the angular speed at the highest point is w= 1.807rad/s
