Chapter 6, Problem 6.19E
Meteor Crater. About 50,000 years ago, a meteor crashed into the earth near present-day Flagstaff, Arizona. Measurements from 2005 estimate that this meteor had a mass of about 1.4 × 108 kg (around 150,000 tons) and hit the ground at a speed of 12 km/s. (a) How much kinetic energy did this meteor deliver to the ground? (b) How does this energy compare to the energy released by a 1.0-megaton nuclear bomb? (A megaton bomb releases the same amount of energy as a million tons of TNT, and 1.0 ton of TNT releases 4.184 × 109 J of energy.)

Suppose that you want to build a tower out of bricks. Suppose that each brick has a mass of 0.5 kg and is 0.1 m tall. You want the tower to be 20 bricks high, and we want to calculate how much energy is required to build it. The physics fact that you need is this: the energy, E (in Joules) required to lift a mass m (in kg) a height h (in m) is E = mgh (where g is the acceleration due to gravity - for this problem, you can take g to be 10 m/s2.)
1. We will assume that no energy is required to place the first brick in the tower, since it is already on the ground. What about the second brick? How high must if be lifted to be placed on top of the first brick? How much energy does that require? What about the third brick? The tenth brick?
A 10 kg toy roller-coaster car is 9 meters above the ground and moves at a speed 15 m/s. What is the total energy of the roller-coaster in kilo Joules(1 kJ=1000J)? Write the answer in 2 decimals.

- Since 1995, hundreds of extrasolar planets have been discovered. There is the exciting possibility that there is life on one or more of these planets. To support life similar to that on the Earth, the planet must have liquid water. For an Earth-like planet orbiting a star like the Sun, this requirement means that the planet must be within a habitable zone of 0.9 AU to 1.4 AU from the star. The semimajor axis of an extrasolar planet is inferred from its period. What range in periods corresponds to the habitable zone for an Earth-like Planet orbiting a Sun-like star?arrow_forwardIf the energy in fusion bombs were used to supply the energy needs of the world, how many of the 9-megaton variety would be needed for a year’s supply of energy (using data from Equation 8.7)?
