Question

A car accelerates from rest to 20 m/s in 5 seconds. What is the cars average acceleration?

Answer 1

i think the average acceleration is 4m/s squared

Step-by-step explanation:

a=v-u/t

v=20

u=0

t=5

a=20-0/5

a=4

hope this helps

Answer 2

4m/s2

Step-by-step explanation:

v = u + at

20 = 0 + 5a

a = 20/5

a = 4m/s2
