Taylor is interested in archery. She draws her bow and shoots an arrow at an angle of 50º. It goes a distance of 100 meters. At what other angle could Taylor shoot an arrow with the same amount of force and have it go the same distance? |
| Answer» GET the same range if ONE ANGLE of PROJECTION is Θ then other is 90-Θ As R=u²sin2Θ/g sin2Θ =sin 2 (90-Θ) =sin (180-2Θ ) =sin 2Θ {as sin 180-Θ=sin Θ } | |
