a) What is the average speed in kilometers per second of the Earth around the sun, given that the radius of the Earth's orbit is 1.5×108km?
b) What is the average velocity of the Earth over a year's time?
If a car is traveling at 50 mile/h. Determine the distance that can be traveled after 120 minutes in km.
The Moon is about 3.8 x 10° m from Earth. Traveling at the speed of light, 3.0 x 10° m/s, how long does it take a laser beam to go from Earth to the Moon and back again (in s)? The
same physics was responsible for the noticeable delay in communications signals between lunar astronauts and controllers at the Houston Space Flight Center.
