Problem: You are having a snowball fight with your friend, who is some distance from you. Knowing some physics, you throw one snowball, launching it so that the snowball will hit your friend at the same height from which you let it go. You wait for a short time interval, and then launch a second snowball from the same point, but at a different angle. You want both snowballs to hit your friend in the same place simultaneously. You observe that the maximum height (measured from the launch point) of one snowball is exactly 7.00 times higher than the maximum height reached by the other snowball.
Part A: At what angles were the two snowballs launched, assuming they were launched with the same speed? Use g = 9.80 m/s2.
Please show complete calculation for above problem thank you!
