Ball $A$ is thrown upward at the same time as ball $B$ and with half the speed of ball $B.$ Which of the following is true?

A stone falls from rest. The distance covered by it in the last second of its motion is equal to the distance covered in the first three seconds. What is the height from which the stone was dropped? [Take $g=10 \mathrm{m} {\mathrm{s}}^{–2}$]

A particle is dropped from the top of a high tower, then the distance covered in the fifth second of its fall is

A ball is thrown vertically upwards from the ground. It crosses a point at the height of $25 \mathrm{m}$ twice at an interval of $4 \mathrm{s}$. The ball was thrown with the velocity of
