A ball rolls down a 1.00 m long and 0.40 m inclined plane and falls off down on the floor, 1.20 m.

a) Calculate the speed of the ball when it falls of the plane and the speed in vertical and horizontal direction.

b) Where does the ball land?

c) At what speed and under what angle does it land
concidering horizontal plane?

Given answers are: a: 2.8, 2.6 and 1.1 m/s
b: x=1.0 n
c= 5.6 m/s, 63 degrees.

I used these formulas: Vx=Vocos()
Vy=Vosin ()
y=yo+vyt+1/2gt2
x=x0+vxt

but I dot get right answers :(
