It is almost time for the summer olympics. the olympic hammer throw is a throwing event where the object is to throw a heavy metal ball attached to a wire and handle. the name hammer throw comes from an older contest where men threw a sledge hammer. the hammer have different weights, ranging from 16 pounds down to 8 pounds. imagine there are four hammers to throw: 16, 12, 10, and 8 pounds. if you throw each hammer with the same amount of force, which hammer will move the shortest distance?
a) 8 pounds
b) 10 pounds
c) 12 pounds
d) 16 pounds

The electric potential a distance r from a small charge is proportional to what power of the distance from the charge? a. r^-1 b. r c. r^-2 d. r^2

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
