From the v − t graph, acceleration is the slope. During intervals, slope is constant and changes in steps, matching the stepped graph.
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:
Consider a series of steps as shown. A ball is thrown from 0. Find the minimum speed to directly jump to 5th step
