Anything that doesnt have a change in magnitude or direction is something thats not accelerating. so, for example, a car moving at a constant speed of 5mph on a flat road is an example of an object moving but not accelerating
Answer: I showed you all calculation . You did not attach any graph to question .
Explanation:
Lets first find Velocity
Vr=o m/s
Ve=?
a=1m/s²
t=2s
----------
a=(Vr-V)/t
1m/s²=Vr-0m/s/2s
2m/s=Vr
Lets find the time neeeded to stop :
a=1m/s²
Vs=2m/s
Vf=0m/s
a=(Vf-Vs)/t
t*1m/s²=2m/s
t=2 s
Answer:
The longest straw will be 10.328 meters long.
Explanation:
The water will rise up to a height pressure due to which will balance the atmospheric pressure.
We know
Pressure due to water column of height 'h'
Equating both the values we get the value of height 'h' as
Answer:
21 mpg
Explanation:
So the distance in miles that his car could cover within gas fill up is the difference in odometer reading
d = 54008 - 53762 = 246 miles
So if it takes 11.8 gallons of gas to cover 246 miles then his mile per gallon can be calculated as
246 / 11.8 = 20.85 mpg
<em>GRAVITY !</em>
The object doesn't have to collide or even TOUCH something else in order to feel a gravitational force toward it.
If there's a gravitational force between the space object and ANYTHING else, (and there always is !), then that force will change the object's speed or direction of motion.
