Learning Goal: Application of Newton's Laws including friction, and Work - KE Theorem, Power You have seen this problem several times. Now "Power" is added. A force F' parallel to the incline surface pulls on a suitcase to make it move up on a rough incline, as shown in It is extremely helpful to make a table With Friction like this, fill in each item (use "space Yy F holders" for unknown quantities) F, Nax F Ny~ f\\' = .f;s W, = W, = M = LE=F+F, +f,+W, ZF, =F +F, + /[ +W, Newton's _ _ 2nd law 2F, =ma, EF =ma, The coefficient of kinetic friction is . = 0.63 . The suitcase' mass is m = 9.0 kg , The magnitude of the gravitational acceleration is 9.80 m/s2 . You will find the POWER of the pulling force F' in order for the suitcase to have a constant speed of 14.0 m/s up the incline. In addition to the pulling force F' there are 3 other forces exerted on the suitcase. Here, the frictional force is kinetic f , . Fill in the table on the right side of the figure with three space holders: F, Fy and fk. You can write up X F; and X F,, with F, Fy , or/and fk as space holders. You will apply Newton's Laws (1st or 2nd). Check that the angle in your calculator is in "degrees", sin30 = 0.5. + Part A - Find the magnitude of Fy.
