A train is accelerating at a rate of 2.0 m/s/s. If it accelerates at this rate for 30 seconds, what is the change of velocity? *

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  =

Now,

 Change in velocity  = Acceleration x time

So,

  input the parameters and solve;

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

multiply 2kg by latent heat of vap

force tends to be low and long diustance masses are high
