I know something that a lot of people know but they get in trouble when they try to use it. I got it a long time ago from my old school buddy Ike Newton. I'll tell it to you, but you have to keep it to yourself, don't spread it around, and don't tell a lot of people where you got it.
Here it is:
<em>For every action, there is a reaction that is EQUAL and opposite. </em>
That means that if Jane pushes on the rock with 100 Newtons of force,
then <u><em>The rock pushes on Jane with 100 Newtons of force.</em></u>
It doesn't matter how much Jane's mass is, it doesn't matter what the mass of the rock is, and it doesn't even matter whether Jane is moving, or the rock is moving, or both of them are moving. If there's an action, then you can bet yer britches that there's a RE-action, and the RE-action is EQUAL and OPPOSITE to the action.
Why is this so hard ?
Magnetic. Positively. Bind the atoms to form a molecule of a compound.
Answer:
Part a)
Part B)
since the required static coefficient is more then the given value so it will not remain at rest at highest position.
Part c)
Explanation:
Frictional force on the rock while it is moving upwards along the plane is given as
now we have
now by energy conservation we can say
Work done by friction = loss in mechanical energy
here we know that
Part B)
Now at the maximum height position we can say that force due to static friction must be balanced by its weight along the plane
so we will have
since the required static coefficient is more then the given value so it will not remain at rest at highest position.
Part c)
Again by mechanical energy conservation law
Work done by friction = loss in mechanical energy
here we know that
Explanation:
When,the vehicle has uniform velocity, it's acceleration becomes zero
