A) one strategy in a snowball fight the snowball at a hangover level ground. while your opponent is watching this first snowfall, 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 the one with the same initial speed 14.1 m/s. the first snow ball is thrown at an angle of 52° above the horizontal. at what angle sure you throw the second snowball to make ahead the same point as the first? acceleration of gravity is 9.8 m/s^2. answer in units of °.
b) how many seconds after the first snowball should be through the second so that they arrive on target at the same time? answer in units of s.
