4) A block of mass, m=10 [kg], is on planet Earth and is sliding down an incline with friction at constant speed. It also remains parallel to the surface of the incline, The incline is at an angle, 0=25 . Use g=9.8 [m] / [s] a) (6 pts) Neatly draw all the forces acting on the mass and label them with appropriate names. Hint: You will benefit if you draw your x axis along the incline and your y axis normal to the surface of the incline. b) (6 pts) What is the Fnety? Hint: Write Newton's 2"d Law for the block in the y-direction, given that the y axis is normal to the surface of the incline. Find the y-component of the force of gravity vector. Find all vectors in the y- direction. c) (6 pts) What is the Fnet x? Hint: Write Newton's 2"d Law for the block in the x-direction, given that the x axis is parallel to the surface of the incline. Find the x-component of the force of gravity vector. Find all vectors in the x- direction. 24 d) (6pts) What must be the coefficient of Materials kinetic friction, MK? What are the most Hs MK Steel on steel 0.74 0.57 likely materials the block and incline Aluminum on steel 0.61 0.47 are made out of?
