One strategy in a snowball fight is to throw a snowball at a high angle over level ground. Then while your opponent is watching that snowball, you throw a second one at a low angle timed to arrive before or at the same time as the first one. Assume both snowballs are thrown with a speed of 25.0 m/s. The first is throw at an angle of 70.0o with respect to the horizontal.a) At what angle should the second snowball be thrown to arrive at the same point as the first? Assume air resistance is negligible.b) How many seconds later should the second snowball be thrown after the first for both to arrive at the same time?

One strategy in a snowball fight is to throw a snowball at a high angle over level ground. Then while your opponent is watching that snowball, you throw a second one at a low angle timed to arrive before or at the same time as the first one. Assume both snowballs are thrown with a speed of 25.0 m/s. The first is throw at an angle of 70.0o with respect to the horizontal.
1. a) At what angle should the second snowball be thrown to arrive at the same point as the first? Assume air resistance is negligible.
2. b) How many seconds later should the second snowball be thrown after the first for both to arrive at the same time?
