Two particles A and B are projected with velocities as shown in figure from same horizontal level at t = 0 in vertical plane. Particles collide in air at time t = t₀.

दो कणों A तथा B को t = 0 पर समान क्षैतिज स्तर से चित्र में दर्शाए गए वेगों से ऊर्ध्वाधर तल में प्रक्षेपित किया जाता है। कण समय t = t₀ पर वायु में टकराते हैं।

Q. Neglecting the air resistance, the time of flight of a projectile is determined by ($U\to$ Initial velocity).

1. $U_{vertical}$
2. $U_{horizontal}$
3. $U=U_{vertical}^2+U_{horizontal}^2$
4. $U=U(U_{vertical}^2+U_{horizontal}^2{)}^{12}$

Q. Two straight lines drawn on the same displacement-time graph makes angle ${30}^o$ and ${60}^o$with time axis respectively. Which line represents greater velocity? what is the ratio of the two velocities?
