Using follwing data, draw time-displacement graph for a moving object.
`{:("Time (s)",0,2,4,6,8,10,12,14,16),("Displacement (m)",0,2,4,4,4,6,4,2,0):}`
Use this graph to find average velocity for first 4s, for next 4 s and for last 6 s.

The speed of a car travelling on a straight road is listed below at successive intervals of 1 is : {:("Time(s)",0,1,2,3,4),("Speed (m/s)",0,2,4,6,8):} Which of the following is/are correct? The car travels 1. with a uniform acceleration of 2 m//s^(2) . 2. 16 m in 4 s. 3. with an average speed of 4 m/s. Select the correct answer using the code given below:

i) Find the average velcity in the time intervals a) 0 to 2 s, b) 0 to 4 s, c)2s to 4s

Following table gives the displacement of a car at different instants of time. (a) Draw the displacement-time sketch and find the average velocity of car. (b) What will be the displacement of car at (i) 2.5 s and (ii) 4.5 s?

The following table represents the distance of a car at different instants in a fixed direction. (a) Draw a displacement-time graph and with its help, find whether the motion of the car is uniform or non-uniform? (b) Use graph to calculate : (i) the velocity of car (ii) the displacement of car at t = 2.5 s and t = 4.5 s.
