Question

Two projectiles A and B are projected with same speed at an angle 30% and 60° to the horizontal, tren
which of the following is valid, where T is total time of tight, H is max height and Ris horizontal ange
(A)HA = 3H2
B) T = √3TA (C) R =R
(D) H =3H,​

Answer 1

Answer:

The initial velocity for both the projectiles is the same. Let it be u m/s.

The maximum height of a projectile is given by,

h = \frac{{u}^{2} {sin}^{2} \gamma }{2g}

Where, gamma is the angle of projection, u is the initial velocity and g is the acceleration due to gravity.

Considering one angle at 30° and other as 60°, the ratio will be,

\frac{h1}{h2} = \frac{ {sin}^{2} 30}{{sin}^{2} 60} = \frac{0.25}{0.75} = \frac{1}{3}

Hence, the ratio of the maximum heights projectiles lauched from angles 30° and 60° is 1/3.

i hope this will be helping for u guys thank you

and plzzz dont forget to mark it as brainliest...have a good day,bye bye
