A possible means of space flight is to place a perfectly reflecting aluminized sheet into orbit around the Earth and then use the light from the Sun to push this "solar sail." Suppose a sail of area A 5.9010 m2 and mass m 4,800 kg is placed in orbit facing the Sun. Ignore all gravitational effects and assume a solar intensity of 1,370 W/m2 (a) What force (in N) is exerted on the sail? (Enter the magnitude.) 4.47 If you...
A possible means of space flight is to place a perfectly reflecting aluminized sheet into orbit around the Earth and then use the light from the Sun to push this "solar sail. Suppose a sail of area A-7.00 x 105 m2 and mass m-6.50 x 103 kg is placed in orbit facing the Sun. Ignore all gravitational effects and assume a solar intensity of 1 370 W/m2. (a) What force is exerted on the sail? (b) What is the sail's...
4. A space boat is to be designed such that the solar radiation power on its sail counters the sun's gravitational force. Assume that total weight of the boat is 1000 kg Calculate the surface area of the sail Note: The mean distance between earth and sun is 1.5x1011m, the mass of the sun is 1.99x1030kg, the gravitational constant is 6.67x10-11m/s2, the total solar radiation power density on earth is 1.4 kW/m2 4. A space boat is to be designed...
Part (a) Homework. Unanswered We have a rather small solar sail, which has a mass of 30.0 kg, and a sail area of 60000 m. At a particular distance from the Sun, the Sun's gravitational field is 0.004 N/kg, and the intensity of sunlight is 1000 W/m². Assuming the plane of the sail is perpendicular to the incident light, and the light is 100% reflected, what is the magnitude of the force exerted on the sail by the light? N...
The region around the Earth is filling up with space junk such as old satellites. One idea for cleaning up space involves using sails that create drag (see figure below) Perhaps one day satellites will be equipped with sails that are deployed at the end of their missions. The NASA mission NanoSail-D was launched in 2010 to test this idea. This problem compares the drag on a solar sail due to the Earth's upper atmosphere with the force exerted on...
(a) Imagine that a space probe could be fired as a projectile from the Earth's surface with an initial speed of 4.98 104 m/s relative to the Sun. What would its speed be when it is very far from the Earth (in m/s)? Ignore atmospheric friction, the effects of other planets, and the rotation of the Earth. (Consider the mass of the Sun in your calculations.) (b) What If? The speed provided in part (a) is very difficult to achieve...
In Example 34.6, we imagined equipping 1950DA, an asteroid on a collision course with the Earth, with a solar sail in hopes of ejecting it from the solar system. We found that the enormous size required for the solar sail makes the plan impossible at this time. Of course, there is no need to eject such an object from the solar system; we only need to change the orbit. A much more pressing problem is Apophis, a 300-m asteroid that may be...
Constants In this example we will investigate the viability of using radiation pressure to propel a spacecraft. Suppose a spacecraft with a mass of 2.50 x 10 kg has a solar sail made of perfectly reflective aluminized film with an area of 2.59 x 106 m2 (about 1 square mile). If the spacecraft is launched into earth orbit and then deploys its sail at right angles to the sunlight, what is the acceleration due to sunlight? (At the earth's distance...

You are a visitor aboard the New International Space Station, which is in a circular orbit around the Earth with an orbital speed of vo = 1.10 km/s. The station is equipped with a High Velocity Projectile Launcher, which can be used to launch small projectiles in various directions at high speeds. Most of the time, the projectiles either enter new orbits around the Earth or else eventually fall down and hit the Earth. However, as you know from your...
