Question

a body moves with a velocity of 2m/s for 5s and then its velocity increases uniformly to 10m/s in next 5s. Thereafter its velocity begins to decrease at a uniform rate until it comes to rest after 5s. Plot a velocity time graph for the motion of the body

Answer 1

All the lines are straight lines.

Answer 2

Answer:

The velocity time graph for the motion of the body.

Explanation:

Given that,

Velocity v = 2 m/s

Time t = 5 s

Its velocity increases uniformly to 10 m/s in 5 s.

After that, its velocity begins to decrease at a uniform rate until it comes to rest after 5 s.

According to question,

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

Now, it comes to rest in 5 sec at a constant retardation from C to D.
