Question

A frog is chilling on some lilly pads on a pond. When it wants to jump from one lilly pad to another, it jumps forward at some angle to the water surface. For each jump, the frog can push off hard enough to move forward at 8.86 m/s. If the next lilly pad is 0.536m away, at what angle to the horizontal should the frog jump?

Hints:
-> when a projectile flies, the time it spends moving in the x direction is equal to the time it spends in the y direction
-> you will need to use a double-angle trig identity: sin(x)cos(x) = 0.5 sin(2x)
