Answer: Angular momentum = 23.44
Given,
mass , m =2.5 kg
Linear velocity , v = 12.5 m/s
Diameter ,d = 1.5 m
So ,radius,r = 1.5/2 = 0.75 m
Angular momentum = mass(m) * angular velocity (w)
Angular velocity, w = r* linear velocity (v)
so angular momentum = m*v*r
substituting the given values,
Angular momentum = 2.5 * 12.5 * 0.75 = 23.44 kgm2/s

An 85.0 kg child runs in a straight line towards the edge of a stationary merry-go-round at 2.50 m/s. The merry-go-round is in the shape of a disk and has a diameter of 4.50 m and a mass of 235 kg. The child jumps onto and stays on the merry-go- round. What is the angular momentum of the child before this collision, in kg m2/s? (A) What is the moment of inertia of the merry-go-round, in kg m27 [B) What...
