Last week we measured the muzzle velocity by measuring the drop from a at trajectory. The drop gave us the time in ight, and from that we could get the muzzle velocity. 1 did it three times and averaged the results to get v \"S = 16.54 mils. If I shoot the same Nerf gun straight up the maximum height should be 13.95111. If I shoot it at 45 degrees to the ground, the maximum range should be 2?.3m. When I actually do the experiments, I get much smaller numbers- max height is about (maybe) 6m and the range at 45 degrees is more like 10 or 12m than 2Tm
