Asked by Adam
For safety reasons, park rangers decide to start an avalanche on a mountain slope. They fire an artillery shell at an angle of 430 above the horizontal with an initial speed of 284 m/s. Thirty seconds later they see the explosion. What is the x coordinates of the shell where it explodes, relative to the firing point?

the horizontal (x) component of the launch speed is ... 284 m/s * cos(43ยบ)
the horizontal component is not affected by gravity
... so just multiply by the flight time

That did the trick!
