## Homework Statement

a train is moving at 26.1m/s. 12.7 sec later its speed is 15.9m/s. find the trains acceleration- -.803m/s^2

what additional time would be necessary to bring the train to a stop if it continues to accelerate at the same rate calculated?

-.803=0-15.9/t which is 19.8 seconds

this is the part i can't figure out. i only have two tries left.

find the total distance necessary to bring the train to a complete stop from the beginning initial velocity.

## The Attempt at a Solution

i tried setting it up 26.1=d/32.5 but that wasnt right and now i don't know what else to do.
