A runaway truck ramp is designed to slow to a stop a truck that has failed brakes. Assume that a 3 Mg truck is out of control with failed brakes and enters a runaway ramp that goes up at a constant 30 degrees above the horizontal. If the truck travels L = 400 m up the ramp before coming to a rest, what was its speed when it entered the ramp? Assume the truck rolls without friction up the ramp.

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?
