A train moves from rest to a speed of 25 m/s in 30.0 seconds. What is its acceleration? Please provide the formula and the working

Explanation:

The equation for acceleration is

where vf is the final velocity and v0 is the initial velocity. For us, the final velocity is 25 m/s and the initial is 0 because the train started from resting position. Filling in and solving for a:

so

a = .83 m/s/s
