by how much does the speed of a vehicle moving in a straight line change each second when it is accelerating at 2km/h-s?
at 4km/h-s
at 10 km/h-s???
with explanation THANKS FOR HELP!

Acceleration is the rate of change of speed, so if the car is accelerating a 2 km/h-s, then every second, it is going 2 km/hr faster. The same for 4 and 10.

Think it through, and you find it's a self-answering question, like "who's buried in Grant's tomb."
It changes at the rate it accelerates. If you want to convert to km/h, think of it this way..there are 3600 seconds in an hour. Multiply the acceleration rate by 3600, and you'll get the km/h.

namenot is correct, assuming you mean 2km/h/s.
Rate change is 2km/h per second. Same principle applies to any acceleration (which is always a straight line change).
Therefore,
4km/h/s = 4km/h change is velocity for every second.
10km/h/s = 10km/h change is velocity for every second.

not sure exactly what units you're using but I assume it's kilometre per hour per second. If that's the case then the answer is simply
a)2km/h
b)4km/h
c)10km/h

i don't understand Disney Channel anymore, ever through fact it began sucking. the only guy or woman on there precise now who i for my section care approximately is that David Henrie from Wizards of Waverly place, through fact he's amazing wonderful. besides, right here is your answer: Say hi, be relax, i'm particular they don't need you to be shy or intimidated. additionally, do not act like an insane psycho freak; they probably might desire to deal with rather some ridiculous followers fawning over them and begging for autographs and photos, so i'm particular a extra mature physique of recommendations--performing as though they are regular human beings, through fact heavily, none of them are rather doing something you or i won't be able to do ourselves--could be fresh.

devide each by 3600, the number of seconds in an hour

mayb this will help
d=rt
distance=rate times time
(rate=speed like tem miles per hour etc.)
