To start an avalanche on a mountain slope, an artillery shell is fired with an initial velocity of 310 m/s at 58.0° above the horizontal. It explodes on the mountainside 37.0 s after firing. What are the x and y coordinates of the shell where it explodes, relative to its firing point?

You are given the time so that is nice. Y= Y(0)+V(y0)t(1/2)gt y(0) is zero. V(y0) is 310sin(58) = 262.9(37) (1/2)(9.80)(37)=9546 meters in the air for Y. X=x(0) +V(x0)t x(0) is zero. V(x0)=310cos58=164.3(37)=6078 meters traveled horizontally.
