A ball is shot from the ground into the air. At a height of 9.80 m, its velocity is v = (8.50i + 4.00j) m/s, with i horizontal and j upward. To what maximum height does the ball rise? What total horizontal distance does the ball travel? What is the magnitude of the ball's velocity just before it hits the ground? What is the angle (below the horizontal) of the ball's velocity just before it hits the ground?

a ball is shot straight up into the air and its height above
the ground (in feet) after t seconds is modeled by the functions
s(t)=-16t+127t+8. determines the instantaneous velocity of the ball
two seconds before it hit the ground
