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.
A body falls from a large height. The ratio of distance traveled in each time interval $t_0$ during $t = 0$ to $t = 3\, t_0$ of the journey is
The displacement of a particle as a function of time is shown in Figure. It indicates :-
A wheel of radius $1$ meter rolls forward half a revolution on a horizontal ground. The magnitude of the displacement of the point of the wheel initially in contact with the ground is
A very large number of balls are thrown vertically upwards in quick succession in such a way that the next ball is thrown when the previous one is at the maximum height. If the maximum height is $5\, m$, the number of balls thrown per minute is (take $g = 10\, ms^{-2}$) :-
A car starts from rest and travels with uniform acceleration $\alpha$ for some time and then with uniform retardation $\beta$ and comes to rest. If the total travel time of the car is $‘t’$, the maximum velocity attained by it is given by :-
