how to solve this question

The next three questions relate to the following information. A water slide of height h ends at a height of 1.50m above the water. A girl riding the slide, starts from rest at point A and lands in the water at point B, which is 2.50m from the base of the slide. We can assume the slide is frictionless. h 1.50 m B 2.50 m 15. What is the time the girl is in the air for? Assume the vertical component of velocity is zero as she leaves the slide. Tip: think back to the equations of kinematics. (a) 1.143 s (b) 0.039 s (c) 0.274 s (d) 3.83 s (e) 0.553 s 16. Using conservation of energy, what is the height h of the water slide (see the figure as to what defines h)? (a) 1.04 m (b) 1.76 m (c) 1.25 m (d) 1.56 m (e) 1.19 m 34 17. If the height of the water slide was actually h = 3.20 m, and the girl gave herself an initial speed of 0.540 ms at point A, what will be the horizontal distance between the base of the slide and the splashdown point ? (a) 2.90 m (b) 4.40 m (c) 3.35 m (d) 6.68 m (e) 5.23 m
