A golf ball is launched horizontally at a speed of 11 meters per second and a high of 6.4 m above the ground. How long will it take for the golf ball to reach the ground?

The final momentum of the ball after collision is 13 kg.m/s.

The given parameters;

Let the final momentum of the ball after collision = P₄

Apply the principle of conservation of linear momentum to determine the final momentum of the ball after collision;

total momentum before collision = total momentum after collision

P₁ + P₂ = P₃ + P₄

15 + 3 = 5 + P₄

18 = 5 + P₄

18 - 5 = P₄

13  = P₄

Thus, the final momentum of the ball after collision is 13 kg.m/s.

Explanation:

The vertical axis corresponds to the pressure of a substance, while the horizontal axis corresponds to the temperature. The solid is the substance which contains particles of strong intermolecular force and compaction, typically ionic at a certain temperature, the liquid is the substance which contains relatively compact molecules, however lacks a particular arrangement. The gaseous substance is caused by particles with weak intermolecular forces, causing particle movement and collision with no arrangement whatsoever. The triple point as shown in the diagram, is the phrase on a diagram where each substance: solid, liquid and gas coexist. The critical point is the phase at which the/a substance is indistinguishable between liquid and gaseous states. A substance or elements state is highly dependent on its environment and it’s temperature, of which ultimately affects its kinetic energy within its particles. This is what the graph portrays and represents.

The equilibrium condition allows finding the result for the tension of the cable that supports the block is:

Newton's second law gives a relationship between force, mass and the acceleration of bodies, when the acceleration is zero it is called the equilibrium condition.

A free-body diagram of the forces is shown in the attachment.

Let's write the equilibrium equation for the vertical axis.

        2 [tex]T_1_y[/tex] - f - W = 0

          2 [tex]T_1_y[/tex]  = W + f

Let's use trigonometry to find the tension, as the angle indicates that it is relative to the vertical.

        cos 30 = [tex]\frac{T_1_y}{T_1}[/tex]  

        [tex]T_1_y[/tex]  = T1 cos 30

We substitute.

        2T₁ cos 30 = W + f

         T₁ = m g + f / 2 cos 30

         T₁ = [tex]\frac{6 \ 9.8 + 410}{2 \ cos 30}[/tex]  

         T₁ = 270.66 N

In conclusion using the equilibrium condition we can find the result for the tension of the cable that supports en bloc is:

This question involves the concepts of uniform speed motion and average speed.

The average speed for the entire trip is "26.67 mi/h".

First, we need to find out the total time taken for the entire trip. For that purpose, we will break the entire trip into two halves of uniform speed motion:

[tex]Total\ Time = t_1+t_2\\\\Total\ Time = \frac{s_1}{v_1}+\frac{s_2}{v_2}\\\\Total\ Time = \frac{40\ mi}{20\ mi/h}+\frac{40\ mi}{40\ mi/h}\\\\Total\ Time = 2\ h + 1\ h\\Total\ Time = 3\ h[/tex]

Now, the average speed for the entire trip will be:

[tex]Average\ Speed = \frac{Total\ Distance}{Total\ Time}\\\\Average\ Speed =\frac{80\ mi}{3\ h}[/tex]

Average Speed = 26.67 mi/h

Answer:

Surface tension is the result of water molecules pulling inward with a strong attractive force. This attractive force brings the molecules on the surface of the water close together and causes the surface of the water to be drawn toward the water molecules beneath the surface. Since there are no water molecules above the surface, there are uneven forces. This causes surface tension, allowing the coin to float on the water’s surface.
