one strategy in a snowball fight is to throw
a snowball at a high angle over level ground.
while your opponent is watching this first
snowball, you throw a second snowball at a
low angle and time it to arrive at the same
time as the first
assume both snowballs are thrown with
the same initial speed 32.2 m/s. the first
snowball is thrown at an angle of 51° above
the horizontal. at what angle should you
throw the second snowball to make it hit the
same point as the first? the acceleration of
gravity is 9.8 m/s? .
answer in units of º.
