Q1. A customer sits in an amusement park ride in which the compartment is to be pulled downward in the negative direction of an axis with an acceleration magnitude of 1.34g, with. A 0.577 g coin rests on the customer's knee. Once the motion begins and in unit-vector notation, what is the coin's acceleration relative to (a) ground and (b) customer? (c) How long does the coin take to reach the compartment ceiling, 2.20 m above the knee? In unit-vector notation, what are (d) actual force on the coin and (e) apparent force according to the customer's measure of the coin's acceleration?
Q2. One mole of nickel (6E23 atoms) has a mass of 54 grams, and its density is 8.9 grams per cubic centimeter. You have a long thin bar of nickel, 2.0 m long, with a square cross section, 0.12 cm on the side.
You hang the rod perpendicularly and attach a 231 kg mass to the bottom, and you observe that the bar becomes 1.41 cm longer. Compute the effective stiffness of the interatomic bond, modelled as a "spring".
An object of mass "m" is thrown up an inclined plane of angle "theta" with an initial velocity "v knot". If the motion is resisted by retarding force Fr=-kv (where k is a force coefficient and v the velocity of the object.)
