How to calculate stopping distance?

1.Making estimates. The human eye can detect as few as 9760 photons per second entering the pupil. About how much energy is this, per second? (Assume the photons have a wavelength of 300 nm.) 2...

You have two systems: A. Solid Gold and Water. B. Solid Sodium and Water. Which one can spontaenously release energy and why?

In one bottle you have a mixture of oxygen and hydrogen. In a second one is water. Do they have the same energy? How do you know which one is a fuel and which is not?

A severe storm on January 10, 1992, caused a cargo ship near the Aleutian Islands to spill 29,000 rubber ducks and other bath toys into the ocean. Twelve months later, hundreds of rubber ducks began...

1.) The orbital period of Mars is 2.095 years. Mars is 1.5 au. (distance) Combine the two? 2.) Graph the period in years squared against the distance from the Sun (in au) cubed?

You travel alone from New York to Los Angeles, about 2800 miles. Working from Tables 7.3 and 7.4, how many gallons of gasoline will you use if you travel by car (assuming your car gets average gasoline...

World population is now about 6 billion. The growth rate has been roughly 2% per year since the end of World War II (1945). If a 2% per year growth rate continued, how many years would it take for...

Read each scenario and then answer the question. Scenario A: A 6-kg bucket is raised a distance of 6 m. Scenario B: A 9-kg bucket is raised a distance of 5 m. Scenario C: A 12-kg bucket...

It's about an experiment that asks you to determine the free-fall acceleration, g , using simple pendulum

Light with a wavelength of 673 nm (6.73 x 10-7 m) is incident upon a double slit with a separation of 0.5 mm (5 x 10-4 m). A screen is located 7.3 m from the double slit. (a) At what distance...

1)stiffness of the spring 2)find maximum velocity 3)find the maximum acceleration fn=1\2pi root of k\m fn= natural frequency w=mg g=9.81

In an attempt for a physics teacher to explain the conservation of energy to a student, the teacher goes down a 6.0 m high sliding board. At the bottom, he only travels 7.0 m/s. If the mass of the...

If an object has energy, can it also have work? Explain
