The correct option is (A). The velocity-time graph for a body that starts from rest and moves with a constant acceleration is a straight line that passes through the origin. The graph shows a linear relationship between velocity and time, indicating constant acceleration.
The velocity (v) - time (t) plot of the motion of a body is shown below :
The acceleration (a) - time(t) graph that best suits this motion is :
A wheel of a bullock cart is rolling on a level road, as shown in the figure below. If its linear speed is v in the direction shown, which one of the following options is correct (P and Q are any highest and lowest points on the wheel, respectively) ?
