18pgs\9pbs/soln
This lab uses only simple equipment: stopclock, ball, incline, meter stick, string and some carbon paper. You don't need photogates etc etc. Students first
time a ball down an incline and calculate the angle of the incline and the velocity when the ball starts to freefall. They then calculate V and V1h and V1v. The 2nd step is to calculate the time to hit the ground using the height fallen. Then using the independence of horizontal and vertical speed while falling they calculate how far out from a perpendicular to the start of freefall the ball hits. Students are required to study and prepare thoroughly before shooting and may be asked to use SF and or +/- notation in their work. They are permitted to criticise any lab mates that miss the target by a "lot". Actually V1v has very little influence but is good practice. Last video shows what happens if you don't pay attention in class.
