Question

Q21. The velocity-time graph of two cars A and B is shown below:

) Which car has greater acceleration? Give reason to your answer. (1) Find the velocity of car B at an instant when car A is moving with a velocity of 30 m/s.​

Answer 1

Answer:

Slope of the velocity-time graph gives the acceleration of the body. Since, at the instant earlier than to, slope of car A and car B is same. Thus accelerations of two cars are equal to each other at an instant earlier than to.
