Problem

A grasshopper leaps into the air from the edge of a vertical cliff, as shown in the figure below.The trajectory of the grasshopper is a concave curve, which starts at the edge of the cliff. The initial velocity makes an angle of 50.0 degrees with the horizontal. The vertical distance from the cliff to the highest point of the trajectory is 6.74 centimeters. The horizontal distance from the edge of the cliff to the point where the grasshopper touches the ground is 1.06 meters.

Use information from the figure to find the initial speed of the grasshopper.

Use information from the figure to find the height of the cliff.
