1. The problem statement, all variables and given/known data An artillery shell is fired with initial velocity of 300 m/s at 55 degrees above the horizontal. TO clear an avalanche, it explodes on a mountainside 42 secs after firing. What are the x- and y- coordinates of the shell where it explodes, relative to its firing point? 2. Relevant equations Vox = Vo (cos [tex]\theta[/tex]) Voy = Vo (sin [tex]\theta[/tex]) These could be the wrong equations. Please solve. THANKS!
