You shoot the gun straight up, and it takes 5.0s for the dart to land back at the barrel. What is the maximum horizontal range of your gun? Express answer using two significant figures.arrow_forwardA projectile is shot from ground level at 100 ft/s at a launch angle of θ that is between θ and π /2. Assume that the projectile is acted on by gravity, but not air resistance. Then, in a simple projectile-motion model it can be shown that the projectile lands at a distance R(θ) = 625 sinθcosθ ft from the launch point.
