A car of mass 1000 kg is moving with a velocity of 10 m s−1. If the velocity-time graph for this car is a horizontal line parallel to the time axis, then the velocity of car at the end of 25 s will be :
Diagram shows a velocity – time graph for a car starting from rest. The graph has three sections AB, BC, and CD.
Is the magnitude of acceleration higher or lower than that of retardation? Give a reason.
A ball is thrown up vertically and returns back to thrower in 6 s. Assuming there is no air friction, plot a graph between velocity and time. From the graph calculate
