A top is spun on the floor such that the top precesses around in a circular motion. The top has a mass of m = 0.1 kg and it's center of mass is located a distance of rem = 0.03 m above the tip. The top is thrown with an angular velocity of w = 250 rad/s. a) Calculate the torque felt by the top if it leans an angle ø. b) Find the direction of the torque felt on the top at the angle shown below. c) If the top precesses a full revolution in t = 0.8 seconds, find the moment of inertia of the top. 군 CM

A top is spun on the floor such that the top precesses around in a circular motion. The top has a mass of m
and it's center of mass is located a distance of rem =
0.1 kg
0.03 m above the tip. The top is thrown with an angular
velocity of w =
250 гad/s.
a) Calculate the torque felt by the top if it leans an angle o.
b) Find the direction of the torque felt on the top at the angle shown below.
c) If the top precesses a full revolution in t =
0.8 seconds, find the moment of inertia of the top.
