Examples of newton's laws in soccer

Provide two examples of each of newton's laws in soccer ? (Post grad course)

Optics: Apparent depth due to refractive index change.

A beaker contains water up to height of H1 and K-oil above water up to another height H2. Find the apparent shift in the position of the bottom of the beaker when viewed from above. Refractive index of water is n1 and that of kerosene is n2.

Optics: Application of the lens formula.

A slide projector produces a 500 times enlarged image of a slide on a screen 10m away. If the screen is moved 2m closer, by what distance should the slide be moved towards or away from the lens so that the image remains focused on the screen? What is the magnification in this case? Assume that the projector consists of a single ...continues

Helium and sound waves: Why your voice goes higher with helium.

Helium has an interesting effect on the voice, giving it a high-pitched quality, like donald duck. Assume that the voice is generated by the vocal cord vibrating above a gas filled tube open at one end. Explain why helium raises the frequency of the harmonics that characterise the voice.

Physics I, problems

Use factor labeling 1) A sphere has a radius 1.500m Find its volume in cm^3. Find its suface area in m^2 and in mm^2? 2) A truncated right circular cone has dimensions: upper base diameter =1.50cm lower base diameter = 4.00cm height = 6.00cm Find its volume in cm^3, m^3, mm^3 Velocity-acceleratio ...continues

sound waves

A very large pipe is set up in a science museum. It is open at both ends, and it is large enough to walk inside it. A large loud speaker is set up at one end of the pipe. A student walks along the pipe and makes the following observations. While walking through the entire length of the pipe the student encountered 3 soft zones ...continues

What amount of heat is required to change 10 grams of Ice at -10 degrees Celsius into steam at 120 degrees Celsius?

Physics Problems Kinematics, Acceleration

Show all steps in computation. 1) A VW RAbbit can go from rest to 80.5 km/h (50.0 mi/h) in a modest 8.20 s. How long will it take to speed from 48.3 km/h to 64.4 km/h, along a straight run, if the average acceleration is the same as before? 2)During a takeoff a small plane has an average tangential acceleration of 5.0 m/s^2 ...continues

Rotational Equilibrium and Rotational Dynamics (problem sounds easy)

I'll attach a picture of the problem The sailor in Figure P8.10 weighs 750N. The force F1 exerted by the wind on the sail is horizontal and acts through point B. The weight of the boat is 1250N and acts through point O, which is 0.8m from the point A along the line OA. The force F2 exerted by the water acts through point ...continues

Show all steps: What is the vertical component of the force the man exerts on the box? The man has his right foot on the top corner of the box at 53.1 degrees from the y axis, his left foot is stationary on the ground; the box is 400N. Newtons?_____ direction?______ 1)What is the horizontal component of the force exerte ...continues
