Question

A car increases it's velocity from 2.0m/s to 10m/s in 2.0seconds. What is the car's acceleration?

Answer 1

Answer:

4

Explanation:

we know that,

a=(v-u)/t

so here alos,

a=(10-2)/2=4

Answer 2

Explanation:

initial velocity (u)  = 2m/s

final velocity (v) = 10m/s

time (t)              =  2 sec

acceleration (a) = v-u/t

                          = 10 -2 /2

                          =  8/2

                          =  4

hence the acceleration of the car is 4m/s^2
