Question

A car takes 8s to increase its velocity from 10m/s to 30m/s.what is the average accelaration

Answer 1

its acceleration is 30-10/8=20/8

Answer 2

Answer:

2.5m/s2

Explanation:

average acceleration=change in velocity/time taken

                                    =v-u/time

                                    =10m/s-30m/s/8s

                                    =20m/s/8s

                                    =2.5m/s2
