Answer:

60m/s

Explanation:

Given parameters:

Acceleration  = 2m/s²

Time  = 30s

Unknown:

Change in velocity  = ?

Solution:

Acceleration is the rate of change of velocity with time.

Mathematically;

         Acceleration  = [tex]\frac{Change in velocity }{Time }[/tex]

Now,

 Change in velocity  = Acceleration x time

So,

  input the parameters and solve;

 Change in velocity  = 2 x 30  = 60m/s
