Question

The velocity of a car changes from 7 m/s to 19 m/s in 3s. If the car is uniformly
accelerated, find the acceleration of the car.​

Answer 1

Answer:

4m/s2

Explanation:

u = 7m/s

v = 19m/s

t = 3sec

a =?

a = v-u / t

= 19 - 7 /3

= 12/3

= 4m/s2

Answer 2

Explanation:

given :

initial velocity =7m/s

final velocity =19m/s

time taken =3s

acceleration =?

a=v-u/t

=19-7/3

=12/3

=4m/s

Therefore, the acceleration of the car is 4m/s.
