A crate of mass 9.6 kg is pulled up a rough incline with an initial speed of 1.46 m/s. The pulling force is 102 N parallel to the incline, which makes an angle of 19.9° with the horizontal. The coefficient of kinetic friction is 0.400, and the crate is pulled 5.02 m. a. How much work is done by the gravitational force on thecrate?b. Determine the increase in internal energy of the crate-inclinesystem owing to friction. c. How much work is done by the 100N force on the crate?d. What is the change in kinetic energy of the crate?e. What is the speed of the crate after being pulled 5.00m?

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
