(a) The following table shows x- and y-components of acceleration, velocity, and position:The last line in the table is the answer to part (a).
(b) To determine how far above the ground the ball is when it hits the wall, find out when x = 315,
and evaluate y at that time.(c) The ball’s speed at the moment of impact in part (b) is |v(t)| evaluated at
