Question

Asked Feb 11, 2019

To start an avalanche on a mountain slope, an artillery shell is fired with an initial velocity of 350 m/s at 45.0° above the horizontal. It explodes on the mountainside 39.0 s after firing. What are the x and y coordinates of the shell where it explodes, relative to its firing point?

x =

y =

Step 1

The initial velocity of the artillery shell is 350 m/s at 45.0^{0}. It can be represented in vector form as,

Step 2

Consider the shell is originated from the origin, the x-component of motion are

Step 3

According to second equation of motion along x-axi...
