A. A ball is thrown directly up with an initial speed of 4.00 m/s at y = 0. The maximum height is 0.816 m. The time to achieve the maximum height is 0.985 seconds.
B. From the height h in the previous section A, the ball then drops back to y = 0. Find the time t0 that it takes, and the velocity there (magnitude and direction). Show the final formulas for the quantities, along with the numerical answers.
C. Find the two times the ball is at the height y = 1/2 h. Show the final formula and the numerical answers.
