a grasshopper leaps into the air from the edge of a vertical cliff, as shown in figure. it is given that the angle θ=57 0 and the distances d=0.12 m, and x=2.04 m.
(a) find the initial speed (in m/s) of the grasshopper.
(b) find the height h (in m) of the cliff.
(c) find the speed (in m/s) of the the grasshopper when it is in air at half way down the cliff (h/2 height) on its way to the ground.
