Two trains leave a station at the same time. Train A travels at a constant speed of 16 m/s. Train B starts at 8.0 m/s but accelerates constantly at 1.0 m/s2. After 10.0 seconds, which train has the greater speed? Can someone help me???

You need to do your own homework, sweetie.

6 m/s means for every second the train travels 16 miles. So after 10 seconds it will still travel at 16 miles every second.
Train B starts at 8m/s so for one second it is traveling at 8m/s. At 2 seconds it is traveling at 9 m/s. At 3 seconds it will travel at 10 m/s. And so on up until 10 seconds. I think you can do the rest on your own.
(This is true if the 2 (1.0m/s2)is a typo. Other wise I haven't got a freakin clue.)
Remember the key is to understand the question and not necessarily to get the right answer. If you can learn to understand the question then you will have no need to study if it's on a test.

v0=v-at
8.0m/s=v-1.0m/s2*10.0s
Solve.
