A car is moving on a straight road with uniform acceleration. The speed of the car varies with time as follows :

Time (s)	Speed (m/s)
0 2 4 6 8 10	4 8 12 16 20 24

Draw the speed-time graph by chooding a convenient scale. From this graph :

(i) Calculate the acceleration of the car.

(ii) Calculate the distance travelled by the car in 10 seconds.

A body is moving uniformly in a straight line with a velocity of 5 m/s. Find graphically the distance covered by it in 5 seconds.

The speed-time graph of an ascending passenger lift is given alongside.

What is the acceleration of the lift :

(i) During the first two seconds?

(ii) between second and tenth second?

(iii) during the last two seconds?

The graph given alongside shows how the speed of a car changes with time :

(i) What is the initial speed of the car?

(ii) What is the maximum speed attained by the car?

(iii) Which part of the graph shows zero acceleration?

(iv) Which part of the graph shows varying retardation?

(v) Find the distance travelled in first 8 hours.

Three speed-time graphs are given below :

Which graph represents the case of :

(i) a cricket ball thrown vertically upwards and returning to the hands of the thrower?

(ii) a trolley decelerating to a constant speed and then accelerating uniformly?
