One strategy in a snowball fight is to throw a snowball at a highangle over level ground. Then, while your opponent is watchingthat snowball, you throw a second one at a low angle timedto arrive before or at the same time as the first one. Assumeboth 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 toarrive at the same point as the first? (b) How many secondslater should the second snowball be thrown after the first forboth to arrive at the same time?
