A train is resting on a track when another train with several more cars bumps it and causes it to move forward 10 meters. This is an example of acceleration because:

The answer is below

Explanation:

Acceleration is the rate of change of velocity with respect to time. The S.I unit of acceleration is m/s².

We say that there is acceleration if there is a change of distance or change in velocity (increase or decrease) or both.

The statement above is an example of acceleration because there is a change in velocity. The velocity when the motor was at rest was 0, but an increase in acceleration caused the train to move a distance of 10 meters.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
