SOMEBODY PLEASE help me with these 2 PHYSICS questions. please give me a proper answer.?

Question

1)Suppose a metal sphere is launched up a ramp [incline of 20 degrees] with Vi = 1.5 m/s. The end of the ramp is 1.20 m
above the floor. Calculate the range of the sphere.
2)Now suppose that the ramp is tilted downwards as shown below. Suppose that the sphere leaves the ramp at 1.5 m/s. The bottom of the ramp is 0.90 m above the floor. Calculate the range of the sphere.

Answer 1

In 1), which end of the ramp is 1.20 m above the floor? Is ti the lower end of the ramp, or the upper, that is 1.20 m off the floor?

In 2), the range of the sphere depends on where the upper end of the ramp is.
