Question

An object changes its velocity from 30 m/sec to 40 m/sec in a time interval of 2 seconds. What is its acceleration?​

Answer 1

Explanation:

acceleration is rate of change of velocity

I.e a=change in velocity/time taken

a=10/2=5

Answer 2

Answer:

V=40m/s U=30m/s t=2s

A =v-u÷t

A=40-30÷2

A=10÷2

A=5ms
