In the given figure for a projectile
$y=\left[\frac{x_1 x_2}{x_1-x_2}\right] \tan \theta$
$y=\left[\frac{x_1 x_2}{x_1+x_2}\right] \tan \theta$
$y=\left[\frac{2 x_1 x_2}{x_1+x_2}\right] \cos \theta$
$y=\left[\frac{2 x_1 x_2}{x_1+x_2}\right] \tan \theta$
A body of mass $m$ is thrown upwards at an angle $\theta$ with the horizontal with velocity $v$. While rising up the velocity of the mass after $ t$ seconds will be
A ball is thrown from a roof top at an angle of $45^o$ above the horizontal. It hits the ground a few seconds later. At what point during its motion, does the ball have $(a)$ greatest speed $(b)$ smallest speed $(c)$ greatest acceleration - Explain.
On which does the value of range depend ? On which does the maximum value of range depend ?
A ball is projected upwards from the top of tower with a velocity $50\,\,m{s^{ - 1}}$ making an angle ${30^o}$ with the horizontal. The height of tower is $ 70 \,m$. After how many seconds from the instant of throwing will the ball reach the ground ........ $\sec$
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
