Question

An artillery shell is fired with an initial velocity of 300m/s at 55 degrees above horizontal. To clear an avalanche, it explodes on a mountainside 42.0s after firing. What are the x and y coordinates of the shell where it explodes, relative to its firing point?

Answer 1

Hor vel= 300cos55
Mult this by 42s to get the horizontal (x) distance. (42s btw is a bit ridiculous, but hey ho)

Answer 2

7227.1
