Need help with 49 and 51. Please show work for both problems. Thank you!

, Wm 49. Free-Fall Ride Suppose a freefall ride at an amuse- ment park starts at rest and is in free fall. What is the velocity of the ride after 2.3 5? How far do people on the ride fall during the 2.3s time period? 50. Maximum Height and Flight Time The freefall accelera tion on Mars is about one-third that on Earth. Sup- pose you throw a ball upward with the same velocity on Mars as on Earth. a. How would the ball's maximum height compare to that on Earth? b. How would its flight time compare? 51. Velocity and Acceleration Suppose you throw a ball straight up into the air. Describe the changes in the velocity of the ball. Describe the changes in the acceleration of the ball. 52. Critical Thinking A ball thrown vertically upward continues upward until it reaches a certain position, and then falls downward. The ball's velocity is instanta- neously zero at that highest point. Is the ball accelerat- ing at that point? Devise an experiment to prove or disprove your
