Question

A car increases 20km/h to 30km/h in 10 seconds it's acceleration is

Answer 1

Explanation:

Final velocity (v)=30km/h=8.3m/s

Initial velocity(u)=20km/h=5.5m/s

Time=10s

Acceleration (a)=v-u/t

8.3-5.5/10

0.28m/s^2

Answer 2

Answer:

acceleration = final velocity - initial velocity / time

a = 30 - 20 /10

a = 10 / 10

a = 1
