The 20 kg suitcase A is released from rest at point C of height 3 m from floor ED. The suitcase slides down a friction-less ramp between C and E and continues sliding on the floor until stopping at a certain distance from E.
The coefficient of friction between the floor ED and suitcase A is µ(ED) = 0.4.
Consider g = 9.8 m/s2
Calculate the distance in m from point E reached by suitcase A as it stops.
