Part 1 of 2 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 27.7 m/s. The first snowball is thrown at an angle of 53º above the horizontal. At what angle should you throw the second snowball to make it hit the same point as the first? Note the starting and ending heights are the same. The acceleration of gravity is 9.8 m/s^2.
Part 2 of 2
How many seconds after the first snowball should you throw the second so that they arrive on target at the same time? Answer in units of s.
