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 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 for

both to arrive at the same time?

Step 1

(a). The range for the both snow balls should be equal.

So the angle at which the second snowball be thrown to arrive at the same point as the first is

Step 2

(b) write the expression for time of flight,...
