Questión 2 In the situation illustrated in the figure below, a small package is deposited by a conveyor belt at point A onto a ramp at e = 20° degrees to the horizontal with a velocity of (0.5 m/s. The distance between points A and Bis 2m. B a) Calculate the maximum value u of the kinetic friction coefficient between the package and the ramp AB for which the parcel reaches point B. b) If the actual kinetic friction coefficient between the package and AB and BC is µ4 = 0.5/43, calculate the distance s on the level surface BC at which the package comes to rest.

Question 2 In the situation illustrated in the figure below, a small package is deposited by a conveyor belt at point A onto a ramp at e = 20° degrees to the horizontal with a velocity of (0.5 m/s. The distance between points A and Bis 2 m. C B a) Calculate the maximum value p of the kinetic friction coefficient between the package and the ramp AB for which the parcel reaches point B. b) If the actual kinetic friction coefficient between the package and AB and BC is uk = 0.54, calculate the distance s on the level surface BC at which the package comes to rest. Note: if you haven't been able to solve part a), take the actual kinetic friction coefficient equal to us = 0.15.
