1. Calculate the total displacement travelled between t=0 and t=20s? 2. What is the average velocity of the car between t=0 and t=20s? 3. Calculate the total distance travelled between positions t=10 and t=20s? 4. What is the average speed of the car between t=0 and t=20s? 5. During which time or interval(s) the car was at rest? Explain your answer. 6. In which time interval(s) the car was decelerated? Explain your answer. Do you see that the answer logical? 7. What is the instantaneous acceleration at t=10s? Explain. 8. Draw an estimated graph of its acceleration versus time between t=0 and t=25s. 9. Using the obtained acceleration graph, what is the instantaneous acceleration at t=10s. Compare th value with that obtained in 7. 10. What are the last 3 digits of your mobile number?
