Question 24 Exercise 2B

A body is moving in a straight line and its displacement at various instants of time is given in the following table:

Time (s) 0 1 2 3 4 5 6 7
Displacment (m) 2 6 12 12 12 18 22 24

Plot displacement-time graph and calculate:

(i) Total distance travelled in interval 1s to 5s,

(ii) Average velocity in time interval 1s to 5s.

Answer:
