Question

Figure shows the velocity-time graph of a particle moving in a straight line. State the nature of motion of particle.

Answer 1

V-t graph is a straight line with a constant positive slope from 0 to 4 second. We know, the slope of velocity-time graph gives acceleration. A constant positive slope shows that the body is moving with a constant acceleration till 4 second. From 4 to 6 second, v-t graph is a straight line with a constant negative slope. It shows that the body is moving with a uniform retardation.
