Homework Statement
Homework Equations
I am aware that this can be done via energy methods. However, I wish to do it via:
integral between t1 and t2 of Torques about point (say centre of the wheel) = change in angular momentum of the wheel.
The Attempt at a Solution
The torque is mgR. t1 is zero.
I get that the block hits the floor at t = (square root of 2gh)/g
When I use the change in angular momentum equation, I get w (omega) final as (2.m. (square root of 2gh))/MR but this supposedly is not correct.
Any ideas??
