Yo-Yo man releases a yo-yo from rest and allows it to drop, as he keeps the top end of the string stationary?
Yo-Yo man releases a yo-yo from rest and allows it to drop, as he keeps the top end of the string stationary. The mass of the yo-yo is 0.056 , its moment of inertia is and the radius, , of the axle the string wraps around is 0.0064 .
Through what height must the yo-yo fall for its linear speed to be 0.65 ?
If I is M.I, then
Tension = Ia/r
where a is the acc. of centre of mass.
also Mg - Tension = Ma.
so acc. of centre of mass can be found.. then
v.v = 2ah,
we know the final velocity, & the acc. so Hieght can be found.
(Mg(wight of the yo-yo will not have any torque as its passing throught it;s Centre of Mass, initial velocity of YO-YO is taken to be zero).
