Jay drops the ball from the top of a 60 m tall building with a velocity of 5 m/s. Find the time taken by the ball to reach the ground. Take g = $10m/s^2$.​

Q.

Jay and Viru are standing on the top of the building of height 60 m. Jay throws ball A vertically upwards, and Viru throws ball B vertically downwards with same speed 5 m/s. Find the ratio of time taken by ball A and ball B to reach the ground.

Q. A ball is thrown vertically upward with a velocity of $10\text{m/s}$ from the top of a tower of height of $50\text{m}$. Find the time taken by the ball to reach a height $10\text{m}$ from the ground. (Take $g=10{\text{m/s}}^2$)

Q.

Viru drops a ball while standing on top of a building whose height is 19.6 m.
Find the time taken by the ball to reach the ground.
[Take $g=9.8m/s^2$]

Q.

Viru is standing on the top of the building of height 120 m and throws a ball vertically upwards with a speed of 10 m/s. Find the time taken by the ball to reach the ground. Take g = $10m{s}^{-2}$.

Q. A ball is thrown with a velocity of $5m/s$ towards the ground from the top of a building of height $10m$. What is the change in its speed, when the ball is about to hit the ground? Take $g=10m/s^2$.
