A gunman standing on a sloping ground fires up the slope. The initial speed of the bullet is v0= 390 m/s. The slope has an angle ?= 25° from the horizontal, and the gun points at an angle ? from the horizontal. The gravitational acceleration is g=9.8 m/s2. Let ? = 60°. Find the maximum rangeof the bullet along the slope.
