(a) What is the speed of the ball at the bottom of the first plane?

v2 = vi2 + 2 a (x - xi)

(b) How long doe is take to roll down the first plane?

v = vi + a t

(c) What is the acceleration along the second plane?

v2 = vi2 + 2 a (x - xi)

(d) What is the ball's speed 8.0 m along the second plane?

v2 = vi2 + 2 a (x - xi)
