Question

A car starts from rest, attains 30 m/s in 30 seconds. Calculate the
acceleration of the car.

Answer 1

Explanation:

u= 0

v= 30m

t=30 s

a=?

wkt; a =v-u/t

a =30-0/30

a=0

there fore the acceleration of the car is 0

Answer 2

900

Explanation:

t= 30 second

1= 30m/s

30x 30 = 900

so the car run 900m in 30 seconds
