Group Exercise – Snowball Fight!

Suppose you are on the playground at recess after a big storm and you get into a snowball fight. After experimenting you determine that you can throw one snowball high into the air and while your opponent is watching that snowball, you quickly grab another one and throw it at him/her on a more direct line. Both snowballs are thrown at the same speed (everything you have!) and both arrive at the same time.

Assume that your max velocity is

25.3

m/s. You throw the first snowball at an angle of

68.4

degrees in order to get it to have a high arc and just the right distance. At what angle should you throw the second snowball assuming you throw it at the same velocity? Also, how long (in seconds) after throwing the first snowball should you wait before throwing the second?

Use the projectile trajectory spreadsheet we developed during a previous lecture. Use the Goal Seek tool.Slide2
