An object is thrown vertically upward and has a speed of 20.0 m/s when it reaches two thirds of its maximum height above the launch point. Determine,
a. Make a sketch of the motion, labeling all points and showing all the information you are given or know about it.
b. The velocity of the object at maximum height.
c. The maximum height reached by the object.
d. The initial velocity.
e. How long it takes for the object to reach its maximum height.
f. How long does it take to go down to the same height from which it was thrown.
g. The velocity of the object when it goes down to same height from which it was thrown.
