A 8.0 kg box is released from rest on a frictionless ramp. The box slides from the ramp onto a rough horizontal surface with a friction mk =0.50. The starts at a height of 4 meters (yo = 4 m). What is the formula for force friction?

What is the formula for work (W)?

What type of energy does the box have at the begging on this problem?

Where does the energy go after the box come to rest?

What distance d will the box slide?

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.

When you push downward on a book at rest on a table, you feel an upward force. does this force depend on friction? defend your answer.
