let the plane is flying at some angle theta with west towards north
Now we can use the components
now since plane has to fly towards west so net speed in north must be equal to speed in south for air
So we can say
so plane has to fly in direction 14.5 degree North of west
<span>Kinetic
energy is the energy that is possessed by an object that is moving. It is
calculated by one-half the product of the mass and the square of the velocity
of the object. We need to determine the velocity of the cart that is moving.

First, we use Newton's Second Law of motion;
<span>Force = ma
200 = 55a
a = 3.64 m/s^2
Then, from the kinematic equation we calculate the velocity;
v^2 = v0^2 + 2ax
where v is the final velocity, v0 is the initial veocity (zero since it initially start at zero), a is the acceleration ( 3.64 m/s^2) and x is the distance traveled.
v^2 = 0^2 + 2 (3.64) (10)
v^2 = 72.73 m^2 / s^2
v = 8.53 m / s
KE = mv^2 / 2
KE = 1/2 (55) (8.53^2)
KE= 2000 J</span>
Answer: Option (E)
Explanation:
There are only two forces acting on the car: The force of gravity, which point down, and the normal force generated by the interaction of the car and the ramp, which points perpendicular to the ramp.
,
:mass of the car ; 
:angle of the ramp.
: gravity's acceleration.
is constante since all parameters are constants.
So, since the force of gravity is also constant, the net force acting on the car is constant. Since velocity decreases over time and the car stars moving down, the force is pointing down the ramp.
A black hole doesn't suck things in any harder than any other object does, unless you're closer to it. The Earth hasn't gotten any closer to the sun in many years. This is not the reason for climate change.
On the average throughout a month, the moon appears to move
through the sky with a period of about 24 hours 48 minutes.
So if Jesse sees the Moon rise around 6:00 PM, he will see it
set the next morning if he is awake around 6:24 AM, and rise
again the next evening around 6:48 PM.
