From the top of a tower,a particle is thrown vertically downwards with a velocity of $10\; m/s$. The ratio of the distances covered by it in the $3^{rd}$ and $2^{nd}$ seconds of the motion is (Take $g = 10\; m/s^2$).

$A$ stone falls freely under gravity. It covers distances $h_1, h_2$ and $h_3$ in the first $5 \ s$,the next $5 \ s$ and the next $5 \ s$ respectively. The relation between $h_1, h_2$ and $h_3$ is:

$A$ body is thrown vertically upwards and reaches its maximum height in $t$ seconds. The total time from the time of projection to reach a point at half of its maximum height while returning (in seconds) is:

$A$ body is released from the top of a tower $H$ metre high. It takes $t$ seconds to reach the ground. The height of the body $\frac{t}{2}$ seconds after release is

Draw graphs $a \to t$,$v \to t$,and $x \to t$ for an object falling freely.

Three particles $A$, $B$, and $C$ are thrown from the top of a tower with the same speed. $A$ is thrown up, $B$ is thrown down, and $C$ is thrown horizontally. They hit the ground with speeds $V_A$, $V_B$, and $V_C$ respectively. Which of the following is correct?
