The path of one projectile as seen by an observer on another projectile is a/an
detailed solution
Correct option is A
Since both projectiles are moving under the influence of gravity. So, relative acceleration of one projectile as seen from other is zero. So, a→=0→ ⇒ axi^+ayj^=0→So, ax=0 ay=0⇒ dVXdt=0 ⇒ dVYdt=0⇒ VX= constant=K1 (say)⇒ VY= constant=K2 (say)⇒ dxdt=K1 ⇒ dydt=K2⇒ dx=K1dt ⇒ dy=K2dt⇒ ∫0xdx=K1∫0tdt ⇒ ∫0ydy=K2∫0tdt⇒ x=K1t …(1) ⇒ y=K2t …(2)Divide (2) by (1), we get y=kx which is the equation of a straight line.Similar Questions
