16. Use the tools at the top of the simulation to measure both the horizontal displacement of the ball and the time the ball spends in the air. Record these values in the table at the beginning of this section 17. Find the horizontal velocity (vz) and the initial vertical velocity (vLy) of the projectile using the kinematics equations. Show your work in the space below. 18. How do these values compare to the values you calculated in Question 157 What conclusions can you draw from this pattern
