Question
Using conservation of energy, find the speed v_b of the block at the bottom of the ramp.
Express your answer in terms of some or all the variables m, v, and h and any appropriate constants.
I would think it would be square root of v^2+2gh but its telling me no

PE=KE (if there is no friction)
mgh=mv^2/2
v=sqroot(2gh)
mgh=mv^2/2
v=sqroot(2gh)
;)
vb= square root v^2 +2gh

The correct answer is:
vb= square root (v^2+2gh)
Do not forget the parenthesis under the square root sign!
vb= square root (v^2+2gh)
