Projectile motion maximum height and time of flight

Two particles A and B are projected from ground at an angle of \( 30^\circ \) with the horizontal with velocity \( 20\text{ m/s} \) and \( 40\text{ m/s} \) respectively. The maximum height and time of flight are both greater for which particle?
A
B
Same for both
Data insufficient

Solution:

Maximum height \( H \propto u^2 \) and Time of flight \( T \propto u \) for a given angle. Since particle B has a larger initial velocity, both parameters are greater for B.
