Rectangular Components of a Vector
A vector can be expressed as an ordered pair (x,y) where x is the x-coordinate, and y is the y-coordinate of a rectangular system.
It can also be given as a magnitude-angle pair (r,θ) where θ is measured from the positive x-axis. It's also known as polar coordinates.
The conversion from polar to rectangular coordinates is:
[tex]x=r\cos \theta[/tex]
[tex]y=r\sin\theta[/tex]
We are given the vector as a magnitude r=47.3 m and at an angle θ=39.4°. The x-component of the vector is:
[tex]x=47.3\cos (39.4^\circ)[/tex]
Using a scientific calculator to find the trigonometric function:
[tex]x=47.3\cdot 0.7716[/tex]
x=36.5 m

A 45 kg puggle and a 130 kg puma are at a standoff (staring at each other) with a distance 70 m between them. What is the magnitude of the force of gravity between the puggle and the puma?
Answer:
It should be normal force if it's not right plz forgive me.
Explanation:
The force of gravity between the puggle and the puma is 7.7×10⁻¹¹ Newton.
Given parameters:
Mass of the puggle; m =45 kg
Mass of the puma : M = 130 kg.
Distance between them; r = 70 m.
Then, the magnitude of the force of gravity between the puggle and the puma is; F = GmM/r²
Where, G = universal gravitational constant = 6.6×10⁻¹¹ Si unit.
So, Gravitational force; F = ( 6.6×10⁻¹¹ )×130×45 ÷ (70)² N = 7.7×10⁻¹¹ Newton.
Hence, the magnitude of the force of gravity between the puggle and the puma is 7.7×10⁻¹¹ Newton.

A) In a baseball bat, effort force is smaller and is applied over a large distance, while the resistance force is smaller and is applied over a long distance.
B) In a baseball bat, effort force is smaller and is applied over a large distance, while the resistance force is smaller and is applied over a short distance.
C) In a baseball bat, effort force is larger and is applied over a short distance, while the resistance force is smaller and is applied over a long distance.
D) In a baseball bat, effort force is larger and is applied over a short distance, while the resistance force is smaller and is applied over a short distance.
Answer:
C) In a baseball bat, effort force is larger and is applied over a short distance, while the resistance force is smaller and is applied over a long distance.
Explanation:
The correct answer is option C. This is because unlike in a pry bar, the effort force when swinging a baseball bat is larger and it is applied over a short distance; and in return the resisting force is smaller and it's applied over a long distance.
A student hangs the south pole of a bar magnet near the north pole of
another hanging bar magnet. What do the magnets do?
A. They move away from each other.
B. They move away from each other, then toward each other.
C. They move toward each other.
O D. They do not move.
When the south pole of a bar magnet is near the north pole of another bar magnet, they move toward each other. Therefore, option (C) is correct.
What is a magnet?A magnet can be described as a substance that creates a magnetic field and this magnetic field is the reason for the considerable properties of a magnet. The magnetic force pulls ferromagnetic materials, such as iron, cobalt, etc., and attracts or repels other magnetic substances.
A permanent magnet is composed of a material that is magnetized and produces its own magnetic field such material can be magnetized, and strongly attracted towards a magnet, is known as ferromagnetic, and contain the elements iron, and cobalt.
Each bar magnet possesses a set of North and South poles within them. The south pole of one magnet brings closer to the north pole of another magnet they attract each other and move toward each other.

A 3 kg rubber block is resting on wet concrete. The coefficient of static friction is 0.3. What is the minimum force that must be applied to the block to make the block begin to accelerate?
Answer:
You would have to find the friction force of the rubber block which would be found with the equation of Normal force (mass*gravity) times cooeficient of friction which would give 8.82 N for the amount of friction and because you need more force than 8.82 N (assuming gravity is 9.8)
We need to find the frictional force of the rubber block. This is the normal force (mass × gravity) multiplied by the coefficient of friction, which gives us a friction quantity of 8.82N. This is because it requires a force greater than 8.82N (Gravity is 9.8)
What is coefficient of friction?Mathematically, = F/N, where F represents the frictional force and N represents the normal force. Because F and N are both measured in force units (such as Newtons or Pounds), the coefficient of friction is dimensionless.The friction coefficient is the ratio of the frictional force resisting movement of two contacting surfaces to the normal force pushing the two surfaces together.Both F and N are measured in units of force (such as Newtons or Pounds), so the coefficient of friction is dimensionless. The coefficient of friction has different values for static friction and sliding friction.In stiction, the frictional force resists the force applied to the object and the object remains stationary until the force of stiction is overcome. In kinetic friction, the frictional force opposes the motion of an object.To learn more about coefficient of friction, refer to:

Complete Question
While john is traveling along a straight in interstate highway, he notices that the mile marker reads 242 km. John travels until he reaches the 147 km marker and then retraces his path to the 161 km marker. What is John's resultant displacement from the 242 km marker? How far has he traveled answer in units of km
Answer:
The resultant displacement [tex]\Delta x _{1 , 3} = 81 \ km[/tex]
The total distance traveled by john is [tex]x_t =109 \ km[/tex]
Explanation:
From the question we are told that
The first position of john from the finish point is [tex]x_1 = 242 \ km[/tex]
The second position of john from the finish point is [tex]x_2 = 147 \ km[/tex]
The third position of john from the finish point is [tex]x_3 = 161 \ km[/tex]
Generally the displacement from the 242 km marker is mathematically represented as
[tex]\Delta x _{1 , 3} = x_1 - x_3[/tex]
Here we used [tex]x_3[/tex] instead of [tex]x_2[/tex] because [tex]x_3[/tex] is further than [tex]x_2[/tex] from the finish point
=> [tex]\Delta x _{1 , 3} = 81 \ km[/tex]
Generally the total distance traveled by John is mathematically evaluated as
[tex]x_t = [x_1 - x_2 ] + [x_3 - x_2][/tex]
=> [tex]x_t = [242 - 147 ] + [161 - 147][/tex]
=> [tex]x_t =109 \ km[/tex]

A motorbike has a mass of 200 kg. Both the truck and the motor bike have the same kinetic energy
What is the speed of the motorbike?
A 25 m/s
B 10 m/s
C 125m/s
D 2.5 m/s
Answer:
A - 25m/s
Explanation:
The velocity of the motorbike will be 25 m/s in order to ensure that the truck and the motor bike have the same kinetic energy.
What is Kinetic Energy?The kinetic energy of the body is by the virtue of its motion.
Given is a large truck of mass 5000 kg which is travelling at 5.0 m/s and a motorbike that has a mass of 200 kg. Both the truck and the motor bike have the same kinetic energy.
The Kinetic energy of the truck will be -
E[T] = 1/2 mv² = 1/2 x 5000 x 25 = 2500 x 25 = 62500 joules
Then Kinetic energy of the motorbike will be -
E[M] = 1/2 x 200 x v²
E[M] = 100v² joules
Now-
E[T] = E[M]
100v² = 62500
v² = 625
v = 25 m/s
Therefore, the velocity of the motorbike will be 25 m/s in order to ensure that the truck and the motor bike have the same kinetic energy.
