Aspring is mounted horizontally on an air track, with the left end held stationary. we attach a spring balance to the free end of the spring, pull toward the right, and measure the elongation. we determine that the stretching force is proportional to the displacement and that a force of 6.0 n causes an elongation of 0.030 m. we remove the spring balance and attach a 0.50 kg object to the end, pull it a distance of 0.040 m, release it, and watch it oscillate in shm. find the following quantities: a. the force constant of the springb. the maximum and minimum velocities attained by the vibrating objectc. the maximum and minimum accelerationsd. the velocity and acceleration when the object has moved halfway to the center from its initial positione. the kinetic energy, potential energy, and total energy in the halfway position

Materials will have different energies associated with the electrons inside them. this is related to how strongly bound they are by their work function. if we sandwich a material with a very low energy between two materials with a high energy, we create a trap for an electron. if this trap is very narrow in one direction in comparison to the others, this is approximately a 1-dimensional box that confines the electron. what is the lowest energy of an electron in the box if the thinnest direction across the materials is 4.81 nm?

To practice problem-solving strategy 10.1 for energy conservation problems. a sled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slides a distance d1 down the slope and then covers the distance d2 along the horizontal terrain before stopping. find the coefficient of kinetic friction μk between the sled and the ground, assuming that it is constant throughout the trip.
