A. Consider the point y(0,0) = 30m. This is the crest of the wave. Let’s track where the crest goes after 1 second. How do we do this? Set y(x,1) = 30cm and solve for x. This is the distance the crest has travelled in 1 second, therefore, what is the velocity of the wave? Does this agree with another way to write the velocity of a wave?

In a manufacturing facility boxes are placed, at rest, on a conveyor belt which carries them around a circular path of radius R. After traveling a quarter of a circle, bevelled pi over 2 radians, they slide down a chute. The conveyor belt starts at rest and when a box is placed on it a motor supplies a torque so that the belt has an angular acceleration alpha equals c subscript 1 t. The coefficient of friction between the box and the conveyor belt is mu. What will be the force exerted by the belt on the box as a …

A solid cylinder is mounted above the ground with its axis of rotation oriented horizontally. A rope is wound around the cylinder and its free end is attached to a block of mass 86.0 kg that rests on a platform. The cylinder has a mass of 265 kg and a radius of 0.430 m. Assume that the cylinder can rotate about its axis without any friction and the rope is of negligible mass. The platform is suddenly removed from under the block. The block falls down toward the ground and as it does so, it causes the rope to unwind …

In an earlier chapter you calculated the stiffness of the interatomic "spring" (chemical bond) between atoms in a block of aluminum to be 16 N/m. Since in our model each atom is connected to two springs, each half the length of the interatomic bond, the effective "interatomic spring stiffness" for an oscillator is 4*16 N/m = 64 N/m. The mass of one mole of aluminum is 27 grams (0.027 kilograms). What is the energy, in joules, of one quantum of energy for an atomic oscillator in a block of lead?

Credit-Card Magnetic Strips Experiments carried out on the television show Mythbusters determined that a magnetic field of 1000 gauss is needed to corrupt the information on a credit card's magnetic strip. (They also busted the myth that a credit card can be demagnetized by an electric eel or an eelskin wallet.) Suppose a long, straight wire carries a current of 3.0 A . How close can a credit card be held to this wire without damaging its magnetic strip?
