An object is thrown directly upwards with an unknown initial speed from a height of 2.00m above the ground. It reaches a maximum height of
15.05 m. (use g = 9.81 m/s^2, use proper number of significant
figures)

a. What is the initial speed (in m/s) of the ball?

b. If the ball was thrown with the same initial speed and height at an
angle of 45° instead, what will be the maximum height (in m)?
