Velocity of a body on reaching the point from which it was projected upwards, is
$v = 0$
$v = 2u$
$v = 0.5u$
$v = u$
(d)Body reaches the point of projection with same velocity.
A body falling from the rest has a velocity $v$ after it falls through a height $h$. The distance it has to fall down further for its velocity to become double, will be $……………\,h$
A body is thrown vertically upwards. If air resistance is to be taken into account, then the time during which the body rises is
A ball is dropped vertically from height $h$ and is bouncing elastically on the floor (see figure). Which of the following plots best depicts the acceleration of the ball as a function of time.
A body is projected vertically up with a speed $v_0$ in gravity. The average speed of the body over a time $\frac{v_0}{g}$ calculated from the instant of projection is
Confusing about what to choose? Our team will schedule a demo shortly.
