Question

If a car accelerates from 6 m/s to 12 m/s in 2 seconds, what is the car's acceleration? 1: 2m/s2 2:3m/s2 3:4m/s2 4:5m/s2

Answer 1

Answer:

Explanation:

acceleration = change in velocity / time

                     =( final velocity(v) - initial (u)) / time

                      =( 12-6) / 2

                       =6/2

                        = 3 m/s^2

Answer 2

Given:-

• initial velocity u = 6m/s
• final velocity v = 12m/s
• time t = 2 sec

Find:-

• Acceleration??

Formula:-

$\boxed{a = \frac{v - u}{t} }$

Solution:-

• a= v-u/t
• a= 12-6/2
• a= 6/2
• a= 3m/s^2
