Homework Answers
Part A
The speed of the craft after the acceleration can be calculated as,
Substituting values we get,
Since the speed is close to the speed of light, we can say that there will be time dilation. The dilated time period is given by,
Substituting values we can write, the time on Earth will be,
Add Answer to:

On the Apollo 14 mission to the moon, astronaut Alan Shepard hit a golf ball with a 6 iron. The acceleration due to gravity on the moon is 1/6 of its value on earth. Suppose he hits the ball with a speed of 21 m/s at an angle 25 above the horizontal. Part A You may want to review (Pages 86 - 90). How much farther did the ball travel on the moon than it would have on earth? Express...

You are the science officer on a visit to a distant solar system. Prior to landing on a planet you measure its diameter to be 1.8 x 10' m and its rotation period to be 22.3 hours. You have previously determined that the planet orbits 2.2 x 1011 m from its star with a period of 417 earth days. Once on the surface you find that the free-fall acceleration is 12.2 m/s. Part A What is the mass of the...

Problem 29.16 5 of 7 I Review An observer moving toward Earth with a speed of 0.84 c notices that it takes 4.9 min for a person to fill her car with gas. Suppose, instead, that the observer had been moving away from Earth with a speed of 0.91 c. Part A How much time would the observer have measured for the car to be filled in this case?

Review PartA When the moving sidewalk at the airport is broken, as it often seems to be, it takes you 50 s to walk from your gate to baggage claim. When it is working and you stand on the moving sidewalk the entire way, without walking, it takes 85 s to travel the same distance. How long will it take you to travel from the gate to baggage claim if you walk while riding on the moving sidewalk? Express your...

Part A A 3.7 x 1010 kg asteroid is heading directly toward the center of the earth at a steady 20 km/s. To save the planet, astronauts strap a giant rocket to the asteroid perpendicular to its direction of travel. The rocket generates 5.0 x 10° N of thrust. The rocket is fired when the asteroid is 4.9 x 106 kmaway from earth. You can ignore the rotational motion of the earth and asteroid around the sun. If the mission...
