Does It Make Sense?
Decide whether the statement makes sense (or is clearly true) or does not make sense (or is clearly false). Explain clearly; not all of these have definitive answers, so your explanation is more important than your chosen answer.

Cruise Ship Enery. Suppose we have a spaceship about the size of a typical ocean cruise ship today, which means it has a mass of about l00 million kilograms, and we want to accelerate the ship to a speed of 10% of the speed of light.
a. How Inuch energy would be required? (Hint; You can find the answer simply by calculating the kinetic energy of the ship when it reaches its cruising speed; because 10% of the speed of light is still small compared to the speed of light, you can use thsi formula kinetic energy = 1/2 x m x v2)
b. How does your answer coInpare to total world energy use 5 x 1022 Joules?
c. The typical cost of energy today is roughly 5¢ per 1 million joules. At this price, how much would it cost to generate the energy needed by this spaceship?

3. What is astronomy?
4. What is Geocentric Model?
Part I. We will leam in this class that the distance from the Earth to the Sun is approximately 1AU =
150,000,000 kilometers.
a. Convert this number to meters (1 kilometer = 10° meters) and express it using scientific notation:
150000000000
meters
How else might you express this number? (Millions, billions, etc. ?)
b. A car on the highway drives at 55 mph = 25 meters per second. How long would it take to drive to
the Sun? (Assuming you have a car that works in outer space.)
Use the equation distance = velocity x time, or time = distance / velocity.
Time = distance/velocity = ,
seconds (don't forget to use scientific notation.)
How many days?.
_days
How many years?.
years
