thanks guys that really helped both of them. Kelsi
i can't figure how to set this up. it starts at height h and there's a loop at at ground level with radius r.
problem is that i already used that for velocity (same answer) and it's not unfortunately not the right answer.
it won't let me post it. apparently it seems to be 34cm long, 2cm of which is inserted in in the slot. so the block is 34cmx3cm inserted in a 2cm long slot on the left.
sorry, the units didn't show up. it's .36 m^2, 4.0cm, 45cm, 85cm, 2.4cm
