S. A 79 kg skier starts from rest and skiis straight down (no turning) through a vertical elevation loss of 125m.
a) neglecting air resistance find the final velocity of the skier, (is this reasonable?)
b) If the final velocity is actually only 24 m/s, how much of the original potential energy
is converted to forms other than kinetic? What happens to the "lost energy"?

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?
