A car starting from rest has a velocity of 20 m/s at the end of 1st second , 40m/s at the end of 2nd second and 60m/s at the end of 3rd second. What is it's acceleration ?

hi frnd
we can see uniform acceleration in the car.
as we know, v = u + at
so on putting the values..
20 = 0+a × 1
a= v-u÷t
a= 20-0÷ 1
a = 20 m/s
you can also check it by solving another part
a=40-0/2
a= 20m/s
Or
for 3 observation
a= 60-0/3
a= 20m/s
hope it helps.......
