Which vessels have a tunica media with relatively more smooth muscle than elastic tissue, and an elastic membrane on each face of the tunica media?

A magnet of mass 0.20 kg is dropped from rest and falls vertically through a 35.0 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 1.10 m/s.

A 2kg object accelerated as a net force acts on it. During the 5 seconds this force acts, the object velocity changes from 3 m/s east to 7m/s west. The initial kinetic energy of the object was 9 joules, and the final kinetic energy was 49 joules
