    2) A ball is hit at an angle of 36 degrees to the horizontal from 14 feet above the ground. If it hits the ground 26 feet away (in horizontal distance), what was the initial velocity? Assume there is no air resistance.

    A superball is dropped from a height of 2 m and bounces 90% of its original height on each bounce. (a) When it hits the ground for the eighth time, how far has it traveled? (b) How high off the floor is the ball on the eighth bounce?

  99. MATH VERY URGENT!!!!!!

    1) A ball is hit at an angle of 36 degrees to the horizontal from 14 feet above the ground. If it hits the ground 26 feet away (in horizontal distance), what was the initial velocity? Assume there is no air resistance.
