(6.27 m/s)
What is the final velocity of the ball?
Use the velocity in the xaxis and the final velocity in the yaxis to
find the resultant velocity.
(44.2 m/s)
What angle is the ball traveling at when it hits the ground?
Another way to phrase this is find the angle
the resultant velocity vector makes with the horizontal.
(351.84°)

(160 m)
What is the velocity of the ball, in the yaxis, when it hits the ground?
(39.2 m/s)
What is the final velocity of the ball?
Use the velocity in the xaxis and the final velocity in the yaxis to
find the resultant velocity.
(56 m/s)
What angle is the ball traveling at when it hits the ground?
Another way to phrase this is find the angle
the resultant velocity vector makes with the horizontal.
