A particle is projected from a tower of height $40\ m$ in horizontal direction. Due to wind a constant acceleration is provided to the particle opposite to its initial velocity. If particle hits the ground (at the bottom of the tower) at an angle $37^o$ with horizontal, then find acceleration provided by wind to the particle
$\frac{{40}}{3}m/{s^2}$
$\frac{{80}}{3}m/{s^2}$
$\frac{{10}}{3}m/{s^2}$
$20\,m/{s^2}$
A body is thrown horizontally from the top of a tower of height $5 \,m$. It touches the ground at a distance of $10 \,m$ from the foot of the tower. The initial velocity of the body is ......... $ms^{-1}$ ($g = 10\, ms^{-2}$)
A gun is aimed at a target in a line of its barrel. The target is released and allowed to fall under gravity at the same instant the gun is fired. The bullet will
A bomber plane moves horizontally with a speed of $500\, m/s$ and a bomb released from it, strikes the ground in $10\, sec$. Angle at which it strikes the ground will be $(g = 10\,\,m/{s^2})$
A particle is projected horizontally from a tower with velocity $10\,m / s$. Taking $g=10\,m / s ^2$. Match the following two columns at time $t=1\,s$.
Column $I$ | Column $II$ |
$(A)$ Horizontal component of velocity | $(p)$ $5$ SI unit |
$(B)$ Vertical component of velocity | $(q)$ $10$ SI unit |
$(C)$ Horizontal displacement | $(r)$ $15$ SI unit |
$(D)$ Vertical displacement | $(s)$ $20$ SI unit |
A man projects a coin upwards from the gate of a uniformly moving train. The path of coin for the man will be
