Chapter 7, Problem 19P

GO In Fig. 7-30, a block of ice slides down a frictionless ramp at angle θ = 50° while an ice worker pulls on the block (via a rope) with a force F → r that has a magnitude of 50 N and is directed up the ramp. As the block slides through distance d = 0.50 m along the ramp, its kinetic energy increases by 80 J. How much greater would its kinetic energy have been if the rope had not been attached to the block?

1. A large power cable carries I = 200 A in a straight line East-West for L = 100 m to a device and returns the same current to the power source in the opposite direction. The return path is also straight and runs parallel to the first path directly above it. Up > North ○ South West- East Device 100 m Current Source Down The cable is made of copper with resistivity po = 17.2×10 Qm and mass density pcu = 8960 kg/m³. The cable has a diameter of d = 8.00 cm. a) What force (magnitude and direction) is exerted on the outgoing (+) cable by the magnetic field of the earth? Use a value of B = 40.0 μT for the earth's field, and assume it points, straight north. [1 point] b) Is there a force between the two cables, and is it attractive or repulsive? Briefly explain your answer. [0.5 points] c) How far apart should the two cables be kept so that the force between them is less than 1.0 N? [1 point] d) Suppose the cables are set apart at the distance you got in c). How much torque is exerted on the…
