Chapter 3: Q27P (page 124)

At t = 532.0s after midnight, a spacecraft of mass 1400 kg is located at position (3x105, 7x105,-4x105 ) m, and at that time an asteroid whose mass is 7 x 10 15 kg is located at position (9 x 10 ^ 5, - 3 x 10 ^ 5, - 12 x 10 ^ 5) m. There are no other objects nearby. (a) Calculate the (vector) force acting on the spacecraft. (b) At t=532.0: the spacecraft's momentum wasand at the later time t = 538.0s its momentum was.Calculate the (vector) change of momentum

Masses Mand m attract each other with a gravitational force of magnitude F. Mass m is replaced with a mass 3m, and it is moved four times farther away. Now, what is the magnitude of the force?

Suppose that you are going to program a computer to carry out an iterative calculation of motion involving electric forces. Assume that as usual we use the final velocity in each time interval as the approximate average velocity during that interval. Which of the following calculations should be done before starting the repetitive calculation loop? Which of the calculations listed above should go inside the repetitive loop, and in what order?

(a) Define constants such as

(b) Update the (vector) position of each object.

(c) Calculate the (vector) forces acting on the objects.

(d) Specify the initial (vector) momentum of each object.

(e) Specify an appropriate value for the time step.

(f) Specify the mass of each object.

(g) Update the (vector) momentum of each object.

(h) Specify the initial (vector) position of each object.

A proton and an electron are separated by 1脳10-10m the radius of a typical atom. Calculate the magnitude of the electric force that the proton exerts on the electron and the magnitude of the electric force that the electron exerts on the proton.

A 60 kg person stands on the Earth鈥檚 surface. (a) What is the approximate magnitude of the gravitational force on the person by the Earth? (b) What is the magnitude of the gravitational force on the Earth by the person?

At a particular instant the magnitude of the gravitational force exerted by a planet on one of its moons is 3脳1023N. If the mass of the moon were three times as large, what would be the magnitude of the force? If instead the distance between the moon and the planet were three times as large (no change in mass), what would be the magnitude of the force?
