Question

a body moves with a velocity of 2 m/s for 5 s. then its velocity increases uniformly to 10 m/s in next 5 s. thereafter, its velocity begins to decrease at a uniform rate until it comes to rest after 10 s.
a) plot velocity time graph
b) mark the portion of the graph to show when the motion of the body is uniform and when it is non uniform.
c) from the graph, find the total distance moved by the body in initial 5s, in initial 12 s and in the last 10 s.

Answer 1

Answer:

The body moves from A to B at velocity 2 m/s for 5 s, then it accelerates, from B to C, for 5 s and attains a velocity 10 m/s.
