Problem: So far in your life, you may have assumed that as you are sitting in your chair right now, you are not accelerating. However, this picture is not quite complete! You are on the surface of the Earth, which is rotating.
Required:
Question 1: What is the acceleration of a person sitting in a chair on the equator?
Question 2: At the equator, is your mass times the gravitational acceleration of the Earth greater than, less than, or equal to the normal force exerted on you by the chair you are sitting on? Explain.
Question 3: A classmate of yours asks you why we have ignored this acceleration for the whole first term of physics. Is everything we've learned a lie they ask. Assuage their fears by calculating the percentage difference between the normal force from the chair and your weight while sitting on equator.
Question 4: The latitude of Corvallis is 44.4. What is your acceleration while sitting in your chair?
A force of 10N acts on two blocks on frictionless surface. the first block is 3kg, and the second block is 2kg. what is the acceleration of the system?what force does the 3kg block exert on the 2kg block? what force does the 2kg block exert on the 3k..
Each of two spaceships has proper length L. One of the spaceships travels away from the Earth at speed V. The other follows at a speed 2V and passes the first. Find how long does the second spaceship take to pass the first

Lasers can be utilized to drill or cut material. One such laser generates a series of high-intensity pulses rather than a continuous beam of light. All pulse contains 0.500 J of energy and lasts 10 nanoseconds. The laser fires ten pulses per second.
An open switch, a 6.09 kohm resistor and a 4.15 microfarad capacitor are connected in series across a 17.0V battery. The capacitor starts with no stored charge. Find the time constant. The switch is closed. What is the time until 70 percent of full..
