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 that both snowballs are thrown with a speed of 25.0 m/s. The first is thrown at an angle of 70.0° with respect to the horizontal.(a) At what angle should the second snowball be thrown to arrive at the same point as the first?(b) How many seconds later should the second snowball be thrown after the first in order for both to arrive at the same time?
