You are at a rest stop 250 miles north of New York City. You then travel north at a constant velocity of 65 miles per hour for 2.0 hours.

You are 12 miles north of your base camp when you begin walking north at a speed of 2 miles per hour.

A .500 kg mass is oscillating on a spring with k= 330 N/m. The total energy of it's oscillation is 3.24 J. What is the speed of the mass when it is .100 m from the EP?

A ball is tossed up from a tower 50m above the ground. If the ball has an initial velocity of 30m/s, how long will it take to hit the ground if a = -9.81m/s^2. Help!?

A .150 kg mass is attached to a spring with k=18.9 N/m. At the equilibrium position, it moves 2.39 m/s. How mych mechanical energy does it have?

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?

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

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

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...
