mead, 6. A ball is projected upward at time t = 0 s, from a point on a roof 135 m above the ground. The ball rises, then falls and strikes the ground. The d. The initial velocity of the ball is 30 m/s. Assume air resistance is negligible and g = 10 m/s? . a. Calculate the time required for the ball to rise to its maximum height. b. Calculate the time it takes for the ball to strike the ground c. Calculate the speed with which the ball strikes the ground d. Calculate the maximum height reached by the ball. d. Calculate the total distance traveled by the ballf. Plot the graphs of the vertical velocity and vertical position relative to the ground as a function of time 2401- 2101- Vertical 180 Position 150 (m) relative tol 201- ground 90 50 301 time (s) 80 60 Vertical 40 Velocity (m/s) 20 9 10 time (s) (-20) (-40) (-60) (-80)
