During a snowball ght, your opponent distracts you by throwing a snowball at you with a high arc. She throws snowballs with a speed of 26.5 m/s and the first is thrown at 70.0 degrees. As you are watching the first snowball, she throws a second at a lower angle.
(a) If both snowballs cover the same horizontal distance, at what angle (degrees) should
the second be thrown?
(b) If the second snow ball is going to hit you while your attention is still focused on the first snowball, how soon (s) after the first snowball is thrown must the second be thrown?
In other words, what is the delay between the two throws that will have both arriving at
the same time?
