(5 points) Problem 2 A ball is thrown upward with initial velocity of 12. What maximum height can it reach? What time does it need to reach the maximum height? At what height it was after 2.0 s of motion? (10 points) On Projectile motion: Problem 3 m S An artillery shell is fired with an initial velocity 300.0 at 55.0° above the horizontal. What time it needs to reach its maximum range? What were x and y coordinates of the shell at the instant of time equal to 2/3 of total time of motion? (10 points) Problem 4 If a pitch were thrown horizontally with a speed of 30.0 how far would the ball fall vertically by the time it reached home plate which is 19 m away? (5 points)
