Embibe Experts Solutions for Chapter: Kinematics, Exercise 11: BEGINNER'S BOX - 11

A player throws a ball upwards with an initial speed of $29.4 {\mathrm{ms}}^{-1}$.

To what height does the ball rise and how long does the ball take to return to the player’s hands ? (Take $g=9.8 {\mathrm{ms}}^{-2}$ and neglect air resistance).

A particle is dropped from the top of a tower. The distance covered by it in the last one second is equal to that covered by it in the first three seconds. Find the height of the tower.

Water drops are falling in regular intervals of time from top of a tower of height $9 \mathrm{m}$. If $4^{\mathrm{th}}$ drop begins to fall when $1^{\mathrm{st}}$ drop reaches the ground, find the positions of $2^{\mathrm{nd}}$ & $3^{\mathrm{rd}}$ drops from the top of the tower.
