Yo-Yo man releases a yo-yo from rest and allows it to drop, as he keeps the top end of the string stationary, as shown in the image. The mass of the yo-yo is 0.056kg, its moment of inertia is 2.9 *10-5kg.m2, and the radius, r, of the axle the string wraps around is 0.0064m.
a) What is the linear speed, v, of the yo-yo after it has dropped through a height 0.50hm
b) If the yo-yo%u2019 moment of inertia is increased, does its final speed increase, decrease, or stay the same? Justify your answer. Calculate the final speed for the case I = 3.9*10-5kg.m
