Question

(8) A body is decelerating
uniformly for 5 second to a constant speed and moves with this speed for 30 seconds.
accelerates for 10 sec to acquire the speed it had in the beginning. Draw velocity time graph of the body.​

Answer 1

Answer:

Explanation:

Hey,

Here, the given data is,  

=> For first 5 sec, body is decelerating uniformly  

=> Then, for next 30 seconds it moves with a constant speed or velocity.

=> For last 10 sec,uniformly accelerates to acquire the same speed as it had in the beginning.

So the velocity time graph (V → T) of the body can be drawn as below (image) from the given information.​

Answer 2

Answer:

Explanation:

A body is decelerating   uniformly for 5 second to a constant speed and moves with this speed for 30 seconds.

accelerates for 10 sec to acquire the speed it had in the beginning. Draw velocity time graph of the body.​
