Which of the following can sometimes be 'zero' for a moving body ? (i) average velocity (ii) distance travelled (iii) average speed (iv) displacement

If a body travels half the distance with velocity v_(1) and next half with velocity v_(2), then which one of the following will be the average velocity of the body?

A body travels with a speed of v_1 from A to B and returns with a speed of v_2 from B to A. Derive an expression for the average speed of the body. What will be the average velocity of the body?

Define average velocity and average speed. When does the magnitude of average velocity become equal to the average speed?

The velocity-time graph of a body is given below. Find the average velocity from t = 0 to t = 40 s .

Can a body have a. Zero instantaneous velocity and yet be accelerating? b. Zero average speed but non-zero average velocity? c. Negative acceleration and yet be speeding up? d. Magnitude of average velocity be equal to average speed ?
