A player throws a ball upwards with an initial speed of $29.4\; m s^{-1}$. To what height does the ball rise and after how long (in second) does the ball return to the player's hands $?$ (Take $g=9.8 \;m s^{-2}$ and neglect air resistance).

A body is thrown vertically upwards. Which one of the following graphs correctly represent the velocity vs time?

If a ball is thrown vertically upwards with speed $u$, the distance covered during the last $t$ seconds of its ascent is

A stone thrown upward with a speed $u$ from the top of the tower reaches the ground with a velocity $3u$. The height of the tower is

A body is dropped from a certain height $h$ ( $h$ is very large) and second body is thrown downward with velocity of $5 \,m / s$ simultaneouly. What will be difference in heights of the two bodies after $3 \,s$ is ……. $m$
