Vedclass · Answer

(C) In a velocity-time graph,the slope represents acceleration $(a = dv/dt)$.At point $B$,the graph has a negative slope,which means the acceleration is negative (retardation).According to Newton's second law of motion,$F = ma$.Since the acceleration is negative,the force acting on the body must also be negative,meaning it acts in the direction opposite to the velocity (motion).Therefore,there is a force that opposes the motion of the body.

The velocity-time graph of a body is shown in the figure. It implies that at point $B$
