The weight of bodies may change somewhat from one location to another because of the variation of the gravitational acceleration g with elevation. Accounting this variation using g = a – bz, where a = 9.81 m/s^2 and b = 3.32 x 10^-6 s^-2 and z in m. Determine the weight of an 80-kg person at sea level (z = 0 m), in Denver (z = 1610 m) and on top of Mt. Everest (z = 8848 m)
Two spheres of masses m = 1.07 g and m' = 1.10 * 10 ^ 2 kg are isolated from all other bodies and are initially at rest, with their centers a distance r = 14 cm apart.

A 20 kg child sitting a distance of 5.0 m from the centre of a Merry go round experiences an acceleration of 0.15 m/s^2. What is the speed of the Merry go round?
Kenny gets sent to a distant planet of radius 6.0 x 10^5m, and he tries to find out how big the planet is by kicking a sphere of 0.4 kg. He kicks it (with respect to the ground) at an angle of 45o, with a speed of 30 m/s. If the sphere lands 6 seconds later, what is the mass of that planet? Remember, the gravitational acceleration for this planet isn't the same as Earth's!

At a time when mining asteroids has become feasible, astronauts have connected a line between their 3780-kg space tug and a 6940-kg asteroid. They pull on the asteroid with a force of 611 N. Initially the tug and the asteroid are at rest, 571 m apart. How much time does it take for the ship and the asteroid to meet?
Figure P7.45 shows a picture of American astronaut Clay Anderson experiencing weightlessness on board the International Space Station. a. Most people have the misconception that a person in a spacecraft is weightless because he or she is no longer affected by gravity. Show that this premise cannot be true by computing the gravitational field of the Earth at an altitude of 200 km the typical altitude of a spacecraft in orbit. Compare this result with the gravitational field on the surface of the Earth. b. Why would astronauts in orbit experience weightlessness even if they are experiencing a gravitational field (and therefore a gravitational force)?
