meters per second at 37° above the horizontal. The
horizontal component of the golf ball's initial veloc-
ity is
the horizontal component of the golf ball's initial velocity is 47.92 m/s.
The given parameters;
initial velocity of the golf, v = 60 m/s
angle of projection of the golf, Ф = 37°
The horizontal component of the golf ball's initial velocity is calculated as follows;
[tex]v_0_x = v\times cos(\theta)\\\\[/tex]
[tex]v_0_x[/tex] = 60 m/s x cos (37)
[tex]v_0_x[/tex] = 60 m/s x 0.7986
[tex]v_0_x[/tex] = 47.92 m/s
Thus, the horizontal component of the golf ball's initial velocity is 47.92 m/s.

Water waves with a frequency of 4.5 Hz and a wavelength of 2.0m are traveling across a small harbor that is 200 m wide. How long does it take the waves to travel from one side of the harbor to the over?
Answer:
22.2 seconds
Explanation:
recall that for a regular wave
v = fλ
where v = wave velocity (we need to find this to solve the next part)
f = frequency = 4.5 Hz
λ = wavelength = 2.0m
Substituting these into the equation above,
v = fλ
v = (4.5)(2)
v = 9.0m/s
Also recall that Distance travelled = velocity x time
in our case, we found velocity above (= 9.0 m/s) and the distance across the harbor is given as 200m, hence
Distance travelled = velocity x time
200 = 9.0 x time
time = 200/9.0
time = 22.2 seconds

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:

The motion of a car on a position time graph is represented with a horizontal tine What does this indicate about the car's motion?
Answer:
Position-Time graphs display the motion of a object by showing the changes of velocity with respect to time.
The motion of a car on a position-time graph that is represented with a horizontal line indicates that the car has stopped moving.
A straight line with a positive slope indicates that the car is moving at a constant velocity, and thus the slope is constant. On the other hand, a curve with a changing slope, shows that the velocity is changing.

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

Describe the importance that keystone species have in the environment. What would happen if these species disappeared? How would it affect the local ecosystems?
Answer:
See the answer below
Explanation:
The keystone species of an environment are those species of organisms that are highly influential to the functioning of the ecosystem without whom the ecosystem would be drastically affected, lose its structure, or cease to exist totally.
The influence of keystone species in an environment is disproportionately high when compared to their population in the environment. If keystone species disappeared from an environment, such an environment will find it difficult to perform ecosystem functions with an entirely different structure. In some cases, the ecosystem might cease to exist in its entirety because the species that hold it together are no longer present.
Two blocks, with masses m1= 1.5kg and m2= 2.5kg approach each other
with initial velocities; V1= 2.0 m/s and V2i= 3.0 m/s. The two blocks
collide, in a totally inelastic collision, what is their common final velocity
after collision? *
Answer:
2.625 m/s
Explanation:
This is a momentum question. Momentum is conserved which means that all the starting momentum must be accounted for.
1.5 kg * 2 m/s + 2.5 kg * 3 m's = (1.5 + 2.5)kg * x m/s
3 kg m/s + 7.5 kg m/s = 4 kg * x
10.5 kg m/s = 4 kg x
10.5 / 4 = x
x = 2.625 m/s
inelastic means that after the collision, the masses stick together as though they were one.
