A body falls from rest, its velocity at the end of first second is......... $ft/\sec $ $(g = 32ft/\sec )$
$16$
$32$
$64$
$24$
(b)$v = g \times t = 32 \times 1 = 32ft/\sec $
A horizontal bridge is built across a river. A student standing on the bridge throws a small ball vertically upwards with a velocity $4\,m s ^{-1}$. The ball strikes the water surface after $4\,s$. The height of bridge above water surface is $……\,m$ $\left(\right.$ Take $\left.g=10\,m s ^{-2}\right)$
A body is thrown vertically upwards. If air resistance is to be taken into account, then the time during which the body rises is
If a ball is thrown vertically upwards with speed $u$, the distance covered during the last $t$ seconds of its ascent is
A particle is dropped vertically from rest from a height. The time taken by it to fall through successive distances of $1\, m$ each will then be
Two balls $A$ and $B$ are thrown with same velocity $u$ from the top of a tower. Ball $A$ is thrown vertically upwards and the ball $B$ is thrown vertically downwards. If a ball $C$ is thrown with the same velocity but in the horizontal direction from the top of the tower,If $t_A = 6\ s$ and $t_B = 2\ s$ then it will reach the ground in time $t_c$ equal to……..$s$
