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?

Step 1

**Given**

Angle θ = 66.0 degrees

Angle φ = 35.0 degrees

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

Step 2

**Solution**

Let us consider upward movement as positive

Part A

Path of the projectile

Step 3

Part B

Time of f...
