Two particles are projected from the same point with the same speed at different angles $\theta _1$ and $\theta _2$ to the horizontal. They have the same range. Their times of flight are $t_1$ and $t_2$ respectively.

A

${\theta _1} = 90 - {\theta _2}$

B

$\frac{{{t_1}}}{{\sin \,{\theta _1}}} = \frac{{{t_2}}}{{\sin \,{\theta _2}}}$

C

$\frac{{{t_1}}}{{{t_2}}} = \tan \,{\theta _1}$

D

All of the above

Solution

For same ranges angles of projection are complimentry.

A ball is projected from the ground at an angle of $45^{\circ}$ with the horizontal surface. It reaches a maximum height of $120 m$ and returns to the ground. Upon hitting the ground for the first time, it loses half of its kinetic energy. Immediately after the bounce, the velocity of the ball makes an angle of $30^{\circ}$ with the horizontal surface. The maximum height it reaches after the bounce, in metres, is. . . . .
