13.4) A gun has muzzle speed 140 m/s. Find two angles of elevation that can be used to hit a target 840 m away. (Enter your answers as a comma-separated list. Round your answers to one decimal place. Use g ≈ 9.8 m/s2.) ???? =
A projectile is fired with an initial speed of 250 m/s and angle of elevation 60°. The projectile is fired from a position 120 m above the ground. (Recall g ≈ 9.8 m/s2. Round your answers to the nearest whole number.)
(a) Find the range of the projectile.
(b) Find the maximum height reached.
(c) Find the speed at impact.
