A baseball is thrown by the centerfielder (from shoulder level) to home plate where it is caught (on the fly at shoulder level) by the catcher. At what point is the magnitude of the ball's velocity at a minimum? (air resistance is negligible) just after leaving the centerfielder's hand just before arriving at the catcher's mitt at the top of the trajectory velocity is constant during entire trajectory

A baseball is thrown by the centerfielder (from shoulder level) to home plate
where it is caught (on the fly at shoulder level) by the catcher. At what point is the
magnitude of the ball's velocity at a minimum? (air resistance is negligible) *
just after leaving the centerfielder's hand
just before arriving at the catcher's mitt
at the top of the trajectory
velocity is constant during entire trajectory
A ball is rolled off a table with an initial speed of 0.24 m/s. A stopwatch measures
the ball's trajectory time from table to the floor to be 0.3 s. What is the height of
the table? (g = -9.81 m/s2 and air resistance is negligible)
