Ꮎ X A loaded penguin sled with a mass m = 10.0 kg rests on a plane inclined at angle 0 = 20.0° to the = 0.300, and the horizontal. Between the sled and the plane, the coefficient of static friction is μs coefficient of kinetic friction is μk = 0.100. We want to find the magnitude of force F that is necessary to make the sled move up the plane. 1) Draw a free body diagram of forces acting on the slate (1 point) 2) Write the projection of the gravity force vector on the x and y axis, where x is parallel to the surface and y perpendicular to it as shown on the figure. (1 point) 3) Apply the Newton's second law separately to the x and y axis to obtain two equations. (2 points) 4) From the two equations obtained previously, find the value of the pulling force F necessary to start to move the sled. (2 points) 5) After the sled started to move it reaches a constant velocity v. Compute the force F necessary to maintain the motion of the sled at a non-zero velocity. (1 point)
