Projectile motion is a combination of two one-dimensional motions: one in horizontal and other in vertical direction. Motion in \( 2 D \) means in a plane. Necessary condition for \( 2 D \) motion is that the velocity vector is coplanar to the acceleration vector.
P In case of projectile motion, the angle between velocity and W acceleration will be \( 0^{\circ}\theta180^{\circ} \). During the projectile motion, the horizontal component of velocity remains unchanged but vertical component of velocity is time dependent. Now answer the following questions:
A body is projected at angle of \( 30^{\circ} \) and \( 60^{\circ} \) with the same velocity. Their horizontal ranges are \( R_{1} \) and \( R_{2} \) and maximum heights are \( H_{1} \) and \( H_{2} \), respectively, then
(1) \( \frac{R_{1}}{R_{2}}1 \)
(2) \( \frac{H_{1}}{H_{2}}1 \)
(3) \( \frac{R_{1}}{R_{2}}1 \)
(4) \( \frac{H_{1}}{H_{2}}1 \)
