The horizontal distance or range (R) of an object thrown at an angle e from the horizontal is represented by the equation below where vo is the initial velocity as the object leaves the hand, in feet per second. If vo = 2500 feet per second and e is changed from 13° to 14°, use differentials to approximate the change in range, in feet. 2 R =- - sin20 32 521782 6128 8609 351091
