If your speed changes from 10 km/h to 6 km/h then
you have an acceleration.
Whether it's a positive or negative one completely depends
on which direction you decided to call the positive direction,
when you started considering your speed and its changes.
If you decided to call the direction in which you're traveling
the positive direction, then a decrease in your speed is a
negative acceleration.
But you could just as easily have said that you're traveling
in the negative direction. If you did that, then a decrease in
your speed would be a positive acceleration.
It's completely up to you, and how you define things.
The distance the spring stretches is the answer.
I hope this helps.
Have a nice day.
Answer:
Total charge provided by the battery could be 900000 C.
Maximum current provided by the battery for 37 minutes could be 405.405 A
Explanation:
Rating= 250 A-h
a. Total charge:

Suppose t=1h

We konw that
, replacing:

Total charge provided by the battery could be 900000 C.
b. Maximum current for 37 minutes

Maximum current provided by the battery for 37 minutes could be 405.405 A
on a given inclined we know that net force is given by

here we know that

so here we have


so here acceleration depends directly on angle of inclination
now we also know that if height of the inclined is H and its length is L
then we can write

so the acceleration is given as

so acceleration also depends directly on height of the inclined plane
