Two trains leave a station at the same time train A travels at a constant of 16ms train B starts at 8.0 ms but accelerates constantly at 1o ms After 10.0 seconds which train has the greater speed?

Do your own homework!
The train travelling at the constant speed will still be doing 16ms after 10 seconds
The other train adds 1m per second so, after 10 seconds it will have added 10, 10 + 8 = 18ms. It is going faster.
or :
you can find the final velocity :
final velocity = vi+a(t)
= 8+1(10)
=18 m/s
So Train B is faster.

A toy car accelerates from at a constant rate and covers 75 m along a straight line in 30 seconds what is the final velocity of the car?
The question cannot be answered because a part of it is missing. A toy car accelerates from ... WHAT ... at a constant rate ...
What is the average velocity of a car that accelerates from 15 meters per second to 25 meters per second in 10 seconds?
If the acceleration was constant (15 + 25) /2 = 20 (time does not figure into the averaging at all!)
Is 90 minutes greater than 540 seconds how many minutes are in is 90 minutes greater than 540 seconds?
There are 5400 seconds in 90 minutes which is greater than 540 seconds
Is 15 minutes greater than 850 seconds?
yes 60 Seconds/minute * 15 minutes = 900 seconds. This is 10 seconds greater than 850 seconds.

What was the finally velocity of a car that was traveling at 4ms and accelerated 2ms for seconds?
The question does not specify how many seconds it accelerates for so I would suggest that the answer is 300,000 km per second (approx).The question does not specify how many seconds it accelerates for so I would suggest that the answer is 300,000 km per second (approx).The question does not specify how many seconds it accelerates for so I would suggest that the answer is 300,000 km per second (approx).The question does not specify how many seconds it accelerates for so I would suggest that the answer is 300,000 km per second (approx).
A truck accelerates for 7 seconds and drives 147 m, what was its acceleration?
No
To pass a truck a car initially traveling 25 meters per second accelerates at a constant rate of 3 meters per second squared after 6 seconds how fast is the car traveling?
That's easy, if the car is initially traveling at 25 meters per second and gradually accelerates 3 meters per second for 6 seconds then the car is traveling at 43 meters per second.

Why is ATP product constant?
Cause cells only store about 30 seconds' worth of ATP at any time, so we constantly create, use and recycle ATP molecules. :)
