We can only calculate the velocity theoretically because my school does not have any device that is capable of measuring a projectile traveling at around 350 to 400 m/s

Quoteof measuring a projectile traveling at around 350 to 400 m/sMach 1+ ping-pong balls?Some serious over-estimation there, I think.
Photoresistor would be fine - you have the same delay in detecting at two points, so they cancel out.interval time = (T2+time_delay) - (T1+time_delay) = T2 +time_delay - T1 - time_delay = T2 - T1.Also has the benefit of no tin foil impacting the time by slowing down the ball at all.
Use a photodiode or phototransistor.
Do you think this Miniature Solar Cell - BPW34 will do the trick?

I do believe I mentioned a photodiode or a phototransistor.
Can a ping-pong ball really sustain that?
