Naturally, when a small group of people are solely responsible for the creation of a certain amount
of content, some stuff is going to get missed. I know there are questions out there that are not answered

| 2. P.29 projectile motion
A small dense ball with mass 1.5 kg is thrown with initial velocity <5,8,0> m/s at time
t = 0 at a location we choose to call the origin <0,0,0>m. Air resistance is negligible.
A. When the ball reaches its maximum height, what is its velocity (a vector)?
B. When the ball reaches its maximum height, what is time t?
C. Between the launch at t = 0 and the time when the ball reaches its maximum height, what is the average velocity?
D. When the ball reaches its maximum height, what is it location?
E. At a late time the ball’s height y has return 0, which means that the average value of Vy from t= 0 to this time is zero. At this distance, what is the time t?
F. At the time calculated in part E, when the ball’s height y returns to zero, what is x?
G. At the time calculated in part E, when the ball’s height y returns to zero, what is Vy?
H. What was the angle to the x-axis of the initial velocity?
I. What was the angle to the x-axis of the velocity at the time calculated in part E, when the ball’s height returned to zero?
