Question

To confirm the kinematic equations used to describe projectile motion, a student performed the experiment using the set up you used in the Projectile Motion lab. He got the following experimental values for one of his trials. Height of flight: 66 cm t_23: 0.3448 s X_max: 0.466 m X_min: 0.453 m V_mean: 1.269 m/s Use his measurements above to perform the required calculations below. Calculate the corrected time of flight, t_23corr' s Calculate the theoretical value of the horizontal range this object traveled. m Calculate the theoretical value of the time of flight using the value of the height of flight provided. s

Explanation / Answer

a) t23corr = Xmax/ Vmean = 0.466/1.269 = 0.3672 s

b) X = Vmean* t23 = 1.269*0.3448 = 0.4376m

c) h= 1/2gt^2

0.66= ½*9.8*t^2    

Gives, t= 0.367s
