break the balls initial velocity into vertical and horizontal components.
In the horizontal, how long does it take to go 10 m?
10= vihorizontal*t solve for t, then put it in the vertical equation
h=.57+vivertical*t - 4.9t^2
Jason is practicing his tennis stroke by hitting balls against a wall. The ball leaves his racquet at a height of 57 cm above the ground at an angle of 80° with respect to the vertical.
(a) The speed of the ball as it leaves the racquet is 17 m/s and it must travel a distance of 10 m before it reaches the wall. How far above the ground does the ball strike the wall?
