Hello! I do not understand this question very well but this is the best answer i got...I am very sorry if you do not like this you may report me if you like.
Inertia: One reason why its hard to get up in the morning for school.
Answer:
E.l soni.do es un.a sensac.ión, en el órg.ano del oído, prod.ucida por el movimie/nto ondu>latorio de un m/edio elástico (normal/mente el aire), debi.do a ra.pidísimos ca/mbios de pre.sión, generado/s por el movimiento vibrat.orio d.e un cuerpo sonoro. ... /El ruido se consid/era a to/do sonid.o / o no de.seado.
Explanation:
Answer:
to the left
Explanation:
The gravitational force exerted between two objects is given by:
where
G is the gravitational constant
m1, m2 are the masses of the two objects
r is their separation
And the force is always attractive.
Let's call
the mass on which we are calculating the net force.
The mass on the left is
and it is a distance of
r = 0.500 m
So the gravitational force exerted by this mass on the 10.0 kg mass is
And the direction is to the left.
The other mass is
and its distance is
r = 1.25 m
to the right, so the force exerted by this other mass on the 10.0 kg mass is
And the direction is to the right.
Now, to find the net force, we just have to calculate the algebraic sum, taking into account that the two forces have different directions; taking right as positive direction, the net force is:
And the negative sign means the direction of the net force is to the left.
The force that must be applied to the car is 3200 N
Explanation:
The force exerted on an object is equal to the product between the mass of the object and its acceleration, according to Newton's second law:
where
F is the net force
m is the mass of the object
a is its acceleration
In this problem, we have:
m = 800 kg is the mass of the car
is its acceleration
Therefore, the force that must be applied is

<em>The question is incomplete and doesn't have any requirement. I'm computing the angle at which the dart should have been thrown to hit in the center of the target</em>
Answer:
The dart should be thown with an angle of elevation of
Explanation:
<u>Horizontal and Diagonal Motion</u>
When an object is launched horizontally, its initial vertical speed is zero and the horizontal component remains the same in time. If the initial velocity forms an angle with the horizontal, then the vertical velocity has an initial value which can be positive or negative depending on the angle (above or below the horizontal).
The dart is thrown horizontally and when it reaches the target, 5 meters away, the center of the target was missed by 0.15 meters below. The question doesn't have any requirement, but I'll assume you want to know at what angle should the dart be thrown at the same speed, to be exact on target.
Let's start with the original horizontal launching. The distance x is computed as
The distance y is
We need to find the value of , given x and y. Solving for t in the last equation
Replacing in x
Solving for
Now, let's suppose we try to reach the center of the target by throwing the dart at the same speed but with a certain angle above the horizontal. That way, the formulas for x changes to
Replacing the value of
Operating
Simplifying
Solving for the angle
