Unformatted text preview: 2 sec? (3points) b) What does the particle do at that time: stops, speeds up, or slows down? (1 point) c) At what time does the particle reverse its motion? (3 points) d) What is the position of the particle when it reverses its motion? (3 points) e) At what time does the particle achieves its maximum displacement in the positive x direction? (2 points) 4 8. A block is pushed up a 30° incline by an applied force as shown. The magnitude of the applied force is F = 25 N, the mass of the block is M = 3.0 kg, and the coefficient of kinetic friction is = 0.2. a) Draw a free body diagram for the block. Make sure you clearly label all forces acting on the block and indicate on the figure provided how you chose your x‐y coordinate axes. (4 points) b) Find the magnitude of the resulting acceleration of the block. (12 points) 4 88...
