- To simulate the apparent weightlessness of space orbit, astronauts are trained in the hold of a cargo aircraft that is accelerating downward at g. Why will they appear to be weightless, as measured by standing on a bathroom scale, in this accelerated frame of reference? Is there any difference between their apparent weightlessness in orbit and in the aircraft?arrow_forwardA 200-kg object and a 500-kg object are separated by 4.00 m. (a) Find the net gravitational force exerted by these objects on a 50.0-kg object placed midway between them. (b) At what position (other than an infinitely remote one) can the 50.0-kg object be placed so as to experience a net force of zero from the other two objects?arrow_forwardSolving Problems with Newton’s Laws To sirmulate the apparent weightlessness of space orbit, astronauts are trained in the hold of a cargo aircraft that is accelerating downward at Why do they appear to be weightless, as measured by standing on a bathroom scale, in this accelerated frame of reference?

- A 15.0-kg object is in free fall near the surface of the Earth. What is its weight? What is its acceleration? What is the direction of the gravitational force exerted on it? How do your answers change if the same object is at rest on the surface of the Earth?arrow_forwardFind the ratio of the mass of Jupiter to that of Earth based on data in Table 6.2.arrow_forwardFind the mass of Jupiter based on data for the orbit of one of its moons, and compare your result with its actual mass.arrow_forward
- . As a spacecraft approaches a planet, the rocket engines on it are fired (turned on) to slow it down so it will go into orbit around the planet. The spacecraft’s mass is 2.000 kg, and the thrust (force) of the rocket engines is 400 N. If its speed must be decreased by 1,000 m/s, how long must the engines be fired? (Ignore the change in the mass as the fuel is burned.)arrow_forwardAn astronaut working in space near the International Space Station says she feels weightless. What does she mean? Does the astronaut not have weight?arrow_forwardSuppose you can communicate with the inhabitants of a planet in another solar system. They tell you that on their planet, whose diameter and mass are 5.0103km and 3.61023kg , respectively, the record for the high jump is 2.0 m. Given that this record is close to 2.4 m on Earth, what would you conclude about your extraterrestrial friends’ jumping ability?arrow_forward
- Explain, in terms of the properties of the four basic forces, why people notice the gravitational force acting on bodies fit it is such a comparatively weak force.arrow_forwardAstrology, that unlikely and vague pseudoscience, makes much of the position of the planets at the moment of one's birth. The only known force a planet exerts on Earth is gravitational. (a) Calculate the magnitude of the gravitational force exerted on a 4.20 kg baby by a 100 kg father 0.200 m away at birth (he is assisting, so he is close to the child) (b) Calculate the magnitude of the force on the baby due to Jupiter if it is at its closest distance to Earth, some 6.291011 m away. How does the force of Jupiter on the baby compare to the force of the father on the baby? Other objects in the room and the hospital building also exert similar gravitational forces. (Of course, there could be an unknown force acting, but scientists first need to be convinced that there is even an effect, much less that an unknown force causes it.)arrow_forwardCalculate the mass of the Sun based on data for Earth's orbit and compare the value obtained with the Sun's actual mass.arrow_forward
