Question

A car starts from rest and in 10 seconds is travelling 20 m/ s . what is acceleration ?​

Answer 1

Answer:

v=u+at

20=0+a×2

20=2a

10 m/s^2=a

Answer 2

Answer:2m/s^2

Step-by-step explanation:

acceleration = change in velocity/time

here, initial velocity (u)= 0 (at rest)

         final velocity (v)= 20m/s

         time (t) = 10s

a = (v-u)/t = (20-0)/10 = 20/10 = 2m/s^2
