Question

Using the following velocity time graph of a body answer the following questions. (i) During which time intervals is the body moving with variable velocity ?
(ii) What is the acceleration of the body during the interval 3 s to 5 s?
(iii) What is the displacement of the body in the last four seconds of its motion?

Answer 1

Explanation:

Since, the graph is plotted between time on x-axis and velocity on y-axis, the answer to following question are given below

1. Since the graph is a straight line between 3 and 5. It is inclined before 3 and after 5 as well. There, we conclude that the velocity was variable before 3 and after 5
2. Since, there is no change in velocity, acceleration will be zero from 3 to 5 s
3. It can be find out by calculating areas under the curve from 4 to 7, divide it into a rectangle and a triangle (1*15)+1/2(2*15)=30 m
