YoYo man releases a yoyo from rest and allows it to drop, as he keeps the top end of the string stationary. The mass of the yoyo is 0.056 kg, its moment of inertia is 2.9 X 10^5 kg X m^2 and the radius r of the axle the string wraps around is 0.0064 m. Through what height must the yoyo fall for its linear speed to be 0.60 m/s?

mgh=1/2 mv^2+1/2 *I w^2
but w=v/r
mgh=1/2 mv^2+1/2 *I*v^2/r^2
YOu know m,g, I ,r solve for v 
h= 0.25
