A canon sits at top of 50 m cliff. Canon shoots ball with initial velocity of 60 m/s at 30 degrees above horizontal. Ignore air resistance and g = 10 m/s^2.

Where in the ball's trajectory is speech greatest and where is speed least?

How long does it take to reach highest point and how far from the canon at this point.
