5. (Honors) A racket ball is struck in a way that it leaves the racket with a speed of 4.87 m/s in the horizontal direction. When the ball hits the court, its horizontal distance of 1.95 meters from the racket. Find the height of the racket ball when it left the racket. 6. When the dried-up seed pod of a scotch broom plant bursts open, it shoots out a seed with an initial velocity of 2.62 m/s at an angle of 60.5 degrees above the horizontal. (A) How long does it take for the seed to land?(Assuming it gets shot out from ground level) (B) What horizontal distance does it cover during its flight? 7. A cannon ball is shot at 10 m/s at an angle of 30 degrees. It takes 2.2 seconds for the ball to reach the ground. (A) How high is the cliff that the cannon ball is shot from? (B) How far from the base of the cliff does the ball land? 8. If the same cannon (from question #7) is shot from the same height and same angle and the canon ball lands on another cliff that is lower in 1.7seconds. How high is the lower cliff from the ground? 9. A ball rolls off a table and falls .75m to the floor, landing with a speed of 4 m/s. (A) What is the acceleration of the ball just before it strikes the ground? (B) What was the initial speed of the ball? (C) What initial speed must the ball have if it is to land with a speed of 5 m/s
