To start an avalanche on a mountain slope, an artillery shell is fired with an initial velocity of 340 m/s at 45.0° above the horizontal. It explodes on the mountainside 41.0 s after firing. What are the x and y coordinates of the shell where it explodes, relative to its firing point?

Answer 1

The horizontal velocity component is
Vx = 340 cos 45 = 240.4 m/s.
x coordinate = 240.4 m/s x 41.1 s = __

For the y coordinate, use the initial vertical velocity component
Vyo = 340 sin 45 = 240.4 m/s

y = Voy*41.2 - (1/2) g*(41.2)^2
