I. Solve the following problems completely: Show your complete solution and draw the graph. 1. Sir Labayna drops a stone from the top of a bridge. Four seconds later it strikes the water below. If the final velocity was 60 m/s, a. What was the initial velocity of the stone? b. How high was the bridge? 2. Sir Fabro kicked the ball vertically upward from the ground, and Ma'am Tolentino gazing out of the window sees it coming upward past her at 5m/s. The window is 12m above the ground. a. How high does the ball go above the ground? b. How long does it take to go from a height of 12m to the highest point? 3. A rubber ball thrown vertically upward from the top of a tall building has an initial velocity of 22 m/s. a. Calculate the time required to reach its maximum highest of flight. b. Find the maximum height reached by the rubber ball. c. What are its position and velocity after 4.5 seconds
