(c) $H_{max} = \frac{{{u^2}{{\sin }^2}	heta }}{{2g}}$

According to problem $\,\,\,\frac{{{u_1}^2{{\sin }^2}45^\circ }}{{2g}} = \frac{{{u_2}^2{{\sin }^2}60^\circ }}{{2g}}$

$ \Rightarrow \,\,\frac{{{u_1}^2}}{{{u_2}^2}} = \frac{{{{\sin }^2}60^\circ }}{{{{\sin }^2}45^\circ }}\,$ $ \Rightarrow \,\,\frac{{{u_1}}}{{{u_2}}} = \frac{{\sqrt 3 /2}}{{1/\sqrt 2 }} = \sqrt {\frac{3}{2}.} $

Column $I$	Column $II$
$(A)$ $u_x$ is doubled, $u_y$ is halved	$(p)$ $H$ will remain unchanged
$(B)$ $u_y$ is doubled $u_x$ is halved	$(q)$ $R$ will remain unchanged
$(C)$ $u_x$ and $u_y$ both are doubled	$(r)$ $R$ will become four times
$(D)$ Only $u_y$ is doubled	$(s)$ $H$ will become four times

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 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

Define projectile motion and projectile particle.

The speed of a projectile at its maximum height is half of its intial speed. The angle of projection is ......... $^o$

A ball is thrown at different angles with the same speed $u$ and from the same point. It has the same range in both cases. If $y_1$ and $y_2$ be the heights attained in the two cases, then $y_1+y_2$ equals to
