Question

A car accelerates from rest at 2 m/s2. After 6 seconds, what is the speed of the car?​

Answer 1

Vf = 12 [m/s]

Step-by-step explanation:

To solve this problem we must use the following equation of kinematics.

`v_(f)=v_(o)+a*t\\`

where:

Vf = final velocity [m/s]

Vo = initial velocity = 0 (stars from the rest)

a = acceleration = 2 [m/s²]

t = time = 6 [s]

Now replacing:

`v_(f)=0+2*6\\v_(f)=12[m/s]`
