Problem 1 A famous pirate by the name of "Black Board" was bored one evening, so he got his crew together an invented a game, Pirate Bowling. The game involves a broken cannon (it has a fixed angle of 30 degree) a cannonball, and a platform 5m high. If the velocity of the cannonball is 150m/s what is the maximum distance the cannon can be placed from the platform in order to get a strike (the cannonball hitting the platform)!!!!

150m/s = Velocity

Solution: Cannon Ball Angle= 30° Platform Landing Height= 5m Cannonball Velocity= 150m/s Maximum Distance= ?

sin(30)(150)=75

x=x0+v0t+(1/2)(a)(t)² 5=0+75t-5(t)² 0=-5+75t-5t² Pythagorean Theorem: 23.1 x   15= 346.5m
