Which of the following option is correct for a object having a straight line motion represented by the following graph ?
The object moves with constantly increasing velocity from $O$ to $A$ and then it moves with constant velocity
Velocity of the object increases uniformly.
Average velocity is zero.
The graph shown is impossible.
Acceleration versus velocity graph of a particle moving in a straight line starting from rest is as shown in figure. The corresponding velocity-time graph would be
Let $v$ and a denote the velocity and acceleration respectively of a particle in the dimensional motion
A ball of mass $m_1$ and another ball of mass $m_2$ are dropped from equal height. If time taken by the balls are $t_1$ and $t_2$ respectively, then
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........$sec$
A particle is projected vertically upwards from a point $A$ on the ground. It takes $t_1$ time to reach a point $B$ but it still continues to move up. If it takes $t_2$ time to reach the ground from point $B$ then height of point $B$ from the ground is
