Answer question 1 and explain how you got your answer.
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
Does the answer surprise you?
Calculate the angle a person needs to lean from the vertical when
1. walking a 14 m (radius) circular track at 22 mins per mile, and
Enter to 2 significant figures
Angle with respect to the vertical =
= 0.85
! No, that's not the correct answer.
O
2. running at 4 min per mile.
Enter to 2 significant figures
Angle with respect to the vertical = 6.8
Use 1 mile = 1609.4 m
Sense-making: Do your results for the leaning angle during walking agree with your observations
about people walking on circular tracks?
O
