A parachutist drops freely from an aeroplane for $10\,s$ before the parachute opens  out. Then he descends with a net retardation of $2.5\, m/s^2$. If he bails out of the  plane at a height of $2495\, m$ and $g = 10\, m/s^2$, hit velocity on reaching the  ground will be .......$m/s$

For a particle projected vertically upwards under gravity travels equal distance during $5^{th}$ and $6^{th}$ second of its motion. Find its projection speed........$m/s$ $(g = 9.8\,m/s^2)$

A person travels along a straight road for half the distance with velocity ${v_1}$ and the remaining half distance with velocity ${v_2}$ The average velocity is given by

If a freely falling body travels in the last second a distance equal to the distance travelled by it in the first three second, the time of the travel is........$sec$

Let $v$ and a denote the velocity and acceleration respectively of a particle in the dimensional motion
