A magnet of mass 0.10 kg is dropped from rest and falls vertically through a 20.0 cm copper tube. Eddy currents are induced, causing the copper to warm up. The speed of the magnet as it emerges from the tube is 1.40 m/s. How much heat energy is dissipated to the environment?

A ball of mass m = 2.50 kg, starting from rest, falls a vertical distance h = 55.0 cm before striking a vertically mounted spring, which is then compressed a distance y = 16.0 cm. a) Using conservation of energy, derive the algebraic expression (using symbols) for the spring constant using the provided information. Clearly indicate your chosen initial and final states either on the diagram or in words. b) Determine the spring constant using your algebraic expression from part...
A vertically oriented square loop of copper wire falls from rest in a region in which the field B is horizontal
A vertically oriented square loop of copper wire falls from rest in a region in which the field B is horizontal, uniform, and perpendicular to the plane of the loop, into a field-free region, see (Figure 1). The side length of the loop is s and the wire diameter is d. The resistivity of copper is pr and the density of copper is Pm If the loop reaches its terminal speed while its upper segment is still in the magnetic-field region, find an expression...
