the time needed to hit the bottom

the angle between the ramp and the horizontal

the accel of the ice

I made my coordinate system slant at the angle of the ramp because I thought this would make it less work

(is this okay?)

x0 = 0

x = L

v0 = 0

v = v1

a= A

t = T

v1 = 0 + AT

T = v1/A

v1^2 = 2AL

A = v1^2 / 2L

T = v1 / (v1^2 / 2L)

T = 2L / v1

I got these answers pretty cleanly but I have no idea what I should be doing to get theta since I dont see a way to get the lengths of the potential triangle with hypoteneus L
