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 :
Step 1: Analyze the Velocity-Time Graph
The slope of the velocity-time (v-t) graph represents acceleration. From the given plot:
The velocity increases linearly with time, implying constant acceleration.
Step 2: Match with the Acceleration-Time Graph
Since the acceleration is constant, the acceleration-time (a-t) graph must be a horizontal straight line.
Step 3: Conclusion
The correct acceleration-time graph is option (3)
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) ?
A body of mass 1000 kg is moving horizontally with a velocity of 6 m/s. If 200 kg extra mass is added, the final velocity (in m/s) is:
AB is a part of an electrical circuit (see figure). The potential difference \(V_A - V_B\), at the instant when current \(i = 2\) A and is increasing at a rate of 1 amp/second is:
