Asked Jan 31, 2020

There is a mortar that is firing on soldiers who are approaching up the hill towards the mortar. The mortar is angled at an angle of theta = 66.0 degrees and is fired with a initial velocity of 153ft/s. How far down the hill does the shell strick if the hill subtends an angle phi = 35.0 from the horizontal? Ignore air friction.

How long will the mortar shell remain in the air?

How fast will the shell be traveling when it hits the ground?


Expert Answer

Step 1


Angle θ = 66.0 degrees

Angle φ = 35.0 degrees

Initial velocity u = 153 ft/s = 46.6 m/s
