Which is faster, a bullet with a velocity of 1100. feet per second, or Superman traveling at 1100. miles per hour? Provide the correct velocity for either Superman or the bullet in scientific notation with the correct number of sig figs. You must use the following conversion factors: Density = m/V; 1 L = 1000 mL; 1 L = 1.057 quarts; 1 gallon = 4 quarts; 1 mile = 5280 feet; 1 foot = 12 inches; 1 inch = 2.54 cm; 1 meter = 100 cm; 1 kilometer = 1000 m; 1 g = 0.03527 oz; 1 lb = 16 oz
To determine which is faster, we need to compare the velocities of the bullet and Superman.
Given:
Velocity of the bullet = 1100 feet per second
Velocity of Superman = 1100 miles per hour
To start, let's convert the velocity of the bullet to miles per hour:
1 mile = 5280 feet
1 hour = 60 minutes = 60 seconds
So, to convert feet per second to miles per hour, we can use the following conversion factors:
(1100 feet/second) x (1 mile/5280 feet) x (3600 seconds/1 hour) = 3000 miles/hour
Thus, the bullet has a velocity of 3000 miles per hour.
Now, let's convert the velocity of Superman from miles per hour to feet per second:
(1100 miles/hour) x (5280 feet/1 mile) x (1 hour/3600 seconds) = 1613.33333... feet/second
Since we need to provide the velocity in scientific notation, rounding to the correct number of significant figures, we get:
Velocity of bullet = 3.0 x 10^3 miles/hour
Velocity of Superman = 1.6 x 10^3 feet/second
So, to summarize:
The bullet has a velocity of 3.0 x 10^3 miles/hour.
Superman has a velocity of 1.6 x 10^3 feet/second.
Therefore, the bullet is faster than Superman.
