Question

Problem 3
The velocity-time graph for a car is shown in Fig. 1.35.
Using this graph, calculate
(a) the acceleration within first 2 hours and in the last 2 hours.
(b) the total distance travelled by the car.​

Answer 1

Answer:

(a). acceleration = velocity/time

so slope of velocity-time graph will give us acceleration

(b) distance= velocity×time

therefore , area of curve of velocity-time graph will give distance
