Answer:

a = 9 [m/s²]

Explanation:

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

[tex]v_{f}^{2}=v_{o}^{2} +2*a*x[/tex]

where:

Vf = final velocity = 30 [m/s]

Vo = initial velocity = 0

a = acceleration [m/s²]

x = displacement = 50 [m]

Now replacing:

[tex]30^{2}=0 +2*a*50\\100*a=900\\a=9[m/s^{2} ][/tex]
