2. A 40-lb suitcase has an initial velocity down the ramp of va = 20 ft/s and the coefficient of kinetic friction along AB is = 0.25. Determine: a) The horizontal acceleration of the suitcase. b) The velocity of the suitcase at B. c) The time it takes from A to B. d) The point where it strikes the ground at C (i.e., R). e) The time it takes go from A to C (i.e., A to B plus B to C)? 20 ft 30° 4 ft 1 B -R-
