Question

1.) Time of flight (hint—you have to use vertical equations)

SHOW ALL WORK!

2.) Horizontal velocity

You shoot a nerf dart directly horizontal into the air at a comfortable arm position. Data collection Experiment Two - Horizontal projectile motion Measure the height of arms off the ground. Height of arms 1.00 meters Keeping the arms as steady and level as possible push the thruster in to the projectile dart and record how far it goes in meters. Repeat 3 times trying to be as constant as possible. Trial 1 5.8 m Trial 2 6.4 in Trial 3 5.3 m For the calculation of horizontal velocity, use the average horizontal displacement of the 3 trials Average 93m Performing the following calculations for experiment two.

Answer 1

1) Time of flight = T accleration due to gravity(a) = 9.8 initial velocity(u) = 0 downwards heigh(s) = 1m

So using s = ut + 0.5*a*t² => 1 = 0 + 0.5*9.8*t²

=> t = sqrt(2*1/9.8) = 0.452 sec Answer

2) velocity = distance traveled/time_taken = 5.83 / 0.452 = 12.9 m/s Answer
