In projectile motion, the modulus of rate of change of velocity
is constant
first increases then decreases
first decreases then increases
None of the above
A body is projected at such an angle that the horizontal range is three times the greatest height. The angle of projection is
A stone is thrown at an angle $\theta $ to the horizontal reaches a maximum height $H$. Then the time of flight of stone will be
A projectile crosses two walls of equal height $H$ symmetrically as shown The angle of projection of the projectile is
If $R$ and $H$ represent the horizontal range and the maximum height achieved by a projectile then which of the relation exists?
