(a) Write equations of motion for the grenade (you should have two; one for x-position and one for y-position). Use a fixed frame of reference, with the origin located at the grenade's position at the moment it leaves the launcher. Your equations should be in terms of t and the launcher angle 82.

Question
![A soldier fires a round from a grenade launcher as his Humvee is moving up a 12° incline at VH
= 31 m/s. He notes that at the moment he pulls the trigger, the vehicle has traveled d = 700 m
from the base of the hill, and that his launcher is approximately 5 ft off the ground. The muzzle
velocity of a grenade round is approximately v = 80 m/s. (figure not to scale)
