Question: Packages are thrown down an incline at A with a velocity of 1 m/s. The packages slide along the surface ABC to a convevor belt which moves with a velocity of 2 m/s. Knowing that d = 7.5 in and Î¼k = 0.25 between the packages and all surfaces, determine (a) the speed of the package at Ð¡, (b) the distance a package will slide on the convevor belt before it comes to rest relative to the belt. Fig. P13.14 Answer : (a) Draw the free body diagram of the package while moving down the incline: Calculate the kinetic energy at point A using the following relation: Here, m is mass and is velocity at point A . Substitute 1 m/s for . Calculate the kinetic energy at point A using the following relation: Here, m is mass and is velocity at point B . Calculate the work done in from A to B . Apply the principle of work energy between   #### You've reached the end of your free preview.
