Please explain these 2 questions with proper working.

Question 01 The accompanying figure shows the position versus time curve for a certain particle moving along a straight line. Estimate each of the following from the graph: (a) the average velocity over the interval 0 S r 5 3 (b) the values of t at which the instantaneous velocity is zero (c) the values of t at which the instantaneous velocity is either a maximum or a minimum (d) the instantaneous velocity when .r = 3 s.

(a) How.r high does the rocket travel in 40s? (b) What is the average velocity of the rocket during the rst 40s? (c) What is the average velocity of the rocket during the rst 1000 ft of its ight? (d) What is the instantaneous velocity of the rocket at the end of 405
