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 ball is projected at an angle $45^o$ with horizontal. It passes through a wall of height $h$ at horizontal distance $d_1$ from the point of projection and strikes the ground at a horizontal distance $(d_1 + d_2)$ from the point of projection, then $h$ is
A particle covers $50\, m$ distance when projected with an initial speed. On the same surface it will cover a distance, when projected with double the initial speed ......... $m$
A ball is thrown at an angle $\theta $ and another ball is thrown at an angle $(90^o -\theta )$ with the horizontal from the same point with same speed $40\,ms^{-1}$. The second ball reaches $50\,m$ higher than the first ball. Find their individual heights?
What is range of the projectile particle ? Give velocity of projectile particle at maximum height.
A missile is fired for maximum range at your town from a place $100\, km$ away from you. If the missile is first detected at its half way point, how much warning time will you have ? (Take $g = 10\, m/s^2$)
