Question
A cart rolls down a 2.5 m frictionless ramp in 1.25s after starting from rest at the top. What is the angle of the ramp?

a = g sinθ
s = 1/2 at^2
so, now you have
1/2 * g sinθ * 1.25^2 = 2.5
sinθ = 2.5/7.66
θ = 19°
s = 1/2 at^2
so, now you have
1/2 * g sinθ * 1.25^2 = 2.5
sinθ = 2.5/7.66
θ = 19°
