1) Calculate the average rolling time (troll) for your projectile to travel the measured horizontal distance (d).
2. Calculate the speed, vx, of the projectile as it rolls across the table (vx = d/troll). This should be the speed that the projectile has when it leaves the table.
3. Calculate the time (the falling time, tfall) it took the projectile to move the horizontal distance (range) R. (Since R = vxtfall, tfall = R/vx)
4. Calculate the distance the ball will fall vertically from the table top to the target. ( ) Note: Use g = 9.8 m/s2 for accuracy.
A good measure of comparison (between the measured and calculated heights) is the "percent of difference":
