Question

please provide logical explanation ​

Answer 1

(i) displacement is 20m because at the beginning the object is at 20 and at the end it is at 0 .
(ii) distance is 40+ 20 = 60m as it is the total path travelled
(iii) average velocity = displacement / time = 20 / 8 = 2.5m/ s
(iv) velocity = slope at t= 1 which is 20 /2 = 10 m/s
