A stone is projected up with a velocity of $4.9m/s$ from the top of a tower and it reaches the ground after 3 s. Then the height of that tower is

Q. A particle is projected up with a velocity of 20 m $s^{-1}$ from a tower of height 25 m. Its velocity on reaching the ground is _________ m $s^{-1}$.

Q. A particle is projected up with a velocity of $\sqrt{29}{ms}^{-1}$ from the tower of height 10 m. What is its velocity on reaching the ground?

Q. A stone is projected vertically up from the top of a tower at a velocity 9.8 M per second it reaches the foot of the building in 4 seconds what is the height of the tower and velocity of the stone when it reaches the ground

Q. Single Correct Answer Type
A body of mass $m$ is projected horizontally with a velocity $v$ from the top of a tower of height $h$ and it reaches ground at a distance $x$ from the top of a tower. If a second body of mass $2m$ is projected horizontally from the top of a tower of height $2h$, it reaches the ground at a distance $2x$ from the tower. The horizontal velocity of second body is

Q. A stone is thrown from the top of a tower at an angle of ${30}^0$ up with the horizontal with a velocity of $16m/s$. After $4$ seconds of flight it strikes the ground. Calculate the height of the tower from the ground and the horizontal range of the stone $(g=9.8m/s^2)$
