An artillery shell is fired with an initial velocity of 300 m/s at 55° above the horizontal. To clear an avalanche, it explodes on a mountainside 42.0 s after firing. What are the x and y coordinates of the shell where it explodes, relative to its firing point? 15 m/s. If the brick is in flight for 3s, how tall is the building? ANS. 25m
