A rocket is launched at an angle of 56.0° above the horizontal with an initial speed of 101 m/s. The rocket moves for 3.00 s along its initial line of motion with an acceleration of 29.0 m/s2. At this time, its engines fail and the rocket proceeds to move as a projectile. What...

**precalculus**

If a projectile is fired with velocity v0 at an angle θ, then its range, the horizontal distance it travels (in feet), is modeled by the function R(θ) = v02 sin 2θ 32 . If v0 = 2600 ft/s, what angle (in degrees) should be chosen for the projectile to hit a ...
