Calculating Acceleration of a Train

Until a train is a safe distance from the station it must travel at 5 m/s. Once the train is on open track it can speed up

to 45 m/s. If it takes a train 8 seconds to reach 45 m/s, what is the acceleration of the train? (Round your answer to

the nearest whole number.)

## Answers ( )

Answer:5 m/s (squared)

Explanation:a= change in velocity/time

since the train must travel at 5m/s

then u= 5m/s, v=45m/s, t=8sec

a=v-u/t

a=45-5=40/8

a=5m/s (squared).
