In the figure shown, velocity of the particle at $P \,(g = 10\,m/s^2)$
$40\,m/s$
$30\,m/s$
$50\,m/s$
$50\,cm/s$
At the height $80 \,m$, an aeroplane is moving with $150\, m/s$. A bomb is dropped from it so as to hit a target. At what distance from the target should the bomb be dropped ......... $m$.
A body is projected horizontally from a height with speed $20$ metres/sec. ........ $metres/sec$ will be its speed after $5$ seconds ($g = 10\,\,metres/{\sec ^2})$
An aeroplane is moving with a velocity $u$. It drops a packet from a height $h$. The time $t$ taken by the packet in reaching the ground will be
