A ball was shot from the angles given in the table below. The corresponding ranges (landing at the same height from which it is shot) for three trials are given below as well.
A. Determine the average range and standard deviation for each angle.
B. Next calculate the initial velocity of the projectile for each angle.
I obviously couldn't paste the table here, but the columns are:
angle, range1, range2, range3, average range, standard deviation, average initial velocity
I did part A, so all but the average initial velocities are filled in. I don't understand how you would find them without the time. Can anyone help?
