Q3
A trolley carries a body of weight 25kg. which is kept at a distance of 2.5m from the rear end of the trolley. The trolley starts from rest and accelerates at a constant rate of 2ms−2 If the coefficient of friction between the trolley and the body is 0.1, find the distance of the trolley from the starting point where the body will just slip out of the trolley. Takeg=10ms−2
