List of top Physics Questions on Projectile motion asked in UPSEE

Two identical balls P and Q are projected with same speeds in vertical plane from same point O with making projection angles with horizontal $30^{\circ} $ and $60^{\circ} $ respectively and they fall directly on plane AB at points P' and Q' respectively. Which of the following statement is true about distances as given in options?

A projectile is projected with an initial velocity $\left(4\hat{i}+5\hat{j}\right)m/s$. Here $\hat{j}$ is the unit vector directed vertically upwards and unit vector $\hat{i}$ is in the horizontal direction .Velocity of the projectile (in $m/s$) just before it hits the ground is
