Professional archer Rob N. Hood shoots an arrow at an angle from the top of a 90.0-meter-high cliff. The arrow has an initial speed of 62.0 m/s.
a. If the initial horizontal velocity is 28.0 m/s, what angle (in degrees above the horizontal) did the arrow have when it was shot?
b. How much time does the arrow spend in the air? (Note: You may want to use the quadratic equation for this problem.)
c. Find the velocity and angle of the arrow when it lands.
d. How high does the arrow get above its starting position?
