to start an avalanche on a mountain slope, an artillery shell is fired with an initial velocity of 200 m/s at 55° above the horizontal. It explodes on the mountainside 30 s after firing. What is the x coordinate of the shell where it explodes, relative to its firing point

Hello Guest!

$$x=v\cdot t\cdot cos(55°)=200\ m/s\cdot 30\ s\cdot cos(55°)$$

$$x=3441.5\ m$$
