Light-rail passenger trains that provide transportation within and between cities are capable of modest accelerations. The magnitude of the maximum acceleration is typically 1.3 m/s^2 , but the driver will usually maintain a constant acceleration that is less than the maximum. A train travels through a congested part of town at 6.0 s . Once free of this area, it speeds up to 14 m/s in 8.0 s . At the edge of town, the driver again accelerates, with the same acceleration, for another 16s to reach a higher cruising speed. what is the final speed?

i don't think the problem is correct. Are you sure you posted it correctly?

anonymous · Answer

think i got it
30m/s?

anonymous · Answer

yes its correct (the question)

anonymous · Answer

the problem states the train travels through a congested part of town at 6.0 s. a moving object has speed, not time.

anonymous · Answer

if it is 6m/s, then your answer is correct.

anonymous · Answer

yup sorry. its 6.0 m/s what was the formula used? i goy answer form book.
