A ball is thrown vertically upwards with a velocity of $10m/s$ from a height of $4m$ from the ground. If the air resistance is neglected and $g=9.8m/s^2$, the time taken by the ball to reach the ground is

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. A ball is thrown vertically upwards with a velocity of $10\text{m/s}$. It returns to the ground with velocity of $9\text{m/s}$. If $g=9.8{\text{m/s}}^2$, then the maximum height attained by the ball is nearly (assume air resistance to be uniform)

Q. A ball is thrown vertically upwards with a velocity of $10\text{m/s}$. It returns to the ground with velocity of $9\text{m/s}$. If $g=9.8{\text{m/s}}^2$, then the maximum height attained by the ball is nearly (assume air resistance to be uniform)

Q.

A ball is thrown vertically upwards from the top of a tower with an initial velocity of 19.6m/s. The ball reaches the ground after 5s. Calculate

1. The height of the tower

2. The velocity of ball on reaching the ground.

(Take g=9.8m/s)

Q.

A ball P is dropped vertically and another ball Q is thrown horizontally with the some velocity from the same height and at the same time. If air resistance is neglected, then
