Answer:

1m/s^2

Explanation:

u= 5 m/s

v= 9 m/s

t= 4s

But

a= v-u/t

a= 9-5/4

a= 4/4

a= 1m/s^2

Answer:

1m/s^2

Explanation:

We can use the Kinematic relationship:

[tex]vf=vi+at[/tex]

where:

v f = final velocity;

v i = initial velocity;

a = acceleration;

t = time.

u= 5 m/s  

v= 9 m/s

t= 4s

9 = 5 + 4a

4a = 9-5

4a = 4

divide both side by 4

a = 1

a= 1m/s^2
