X = vt cos (p,y — vt sin <p — 2 the parameter t denoting time measured in seconds, and g, the force of gravity. Take the position of the gun as origin and the horizontal line OL as X-axis. Now, at the end of t seconds, the projectile would be at Q{ OQ — vt) were it 2 not for gravity which pulls… … Hence, tlie locus is a parabola. 7. The distance OL (Fig. 106) from the gun to the point where the pro-jectile strikes the horizontal line is called the range. Derive a formula forcomputing the range when thevelocity v and the angle of ele-vation (p are given. Show thatthe greatest range is…
