Question

A car starting from rest acquires a velocity of 18m/s in 9s .Calculate the acceleration.​

Answer 1

Answer:

2m/s²

Explanation:

since the car starts from rest

U ( initial velocity) = 0

V ( final velocity) = 18m/s

by v = u + at

a = v-u / t

a = 18-0 / 9

a = 18/9

a= 2m/s²

Hope it helps you

Answer 2

Explanation:

A/Q

initial velocity = 0 m/s

final velocity = 18 m/s

time = 9s

acceleration = ?

so, a = v - u / t

=18 - 0 / 9

= 18 / 9

= 2 m / s square .
