Question

derive an equation of motion x=vot+1/2at^2 using v-t graph for uniformly accelerated motion
​

Answer 1

Answer:

Graph plotted with time on x−axis and velocity on y axis is called V−t graph.

V−t graph of a particle having constant acceleration a distance travelled by particle is area under (V−t) graph.
