Thanks. btw what is t1 nd t2 ?
time difference since one timer wil stop when ball crosses first light gate, the other will stop when ball blocks light frm other light gate, and then u can measure either the time diff to find out the time taken to fall h OR u can adjust both light gates to 1 start/stop electronic timer to calculate the t, u just need to draw the diagram and tell measure t through light gates,,,,becuz i havent seen elaboratations of light gates in MS
