Neglecting the air resistance, the time of flight of a projectile is determined by
${U_{vertical}}$
${U_{horizontal}}$
$U = {U^2}_{vertical} + {U^2}_{horizontal}$
$U = U\,{({U^2}_{vertical} + {U^2}_{horizontal})^{1/2}}$
A ball is thrown from the ground to clear a wall $3\,m$ high at a distance of $6\,m$ and falls $18\,m$ away from the wall, the angle of projection of ball is
A projectile is thrown at an angle $\theta$ with the horizontal and its range is $R_1$. It is then thrown at an angle $\theta$ with vertical and the range is $R_2$, then
Two bodies are thrown up at angles of $45^o $ and $60^o $, respectively, with the horizontal. If both bodies attain same vertical height, then the ratio of velocities with which these are thrown is
A body is projected at such an angle that the horizontal range is three times the greatest height. The angle of projection is
In projectile motion, the modulus of rate of change of velocity
