A lift is moving up with a constant retardation of 2 m//s^(2). When its upward velocity is 5 m/s, a boy in the lift tosses a coin, imparting it an upward velocity of 3 m/s, w.r.t. himself. His fingers at the moment of toss are midway between the floor and cciling, whose total height is 2 m. Displacement of coin when it hits the ground is x metre (in earth frame). Value of x is : (g = 10 m//s^(2))

1.	A lift is moving up with a constant retardation of 2 m//s^(2). When its upward velocity is 5 m/s, a boy in the lift tosses a coin, imparting it an upward velocity of 3 m/s, w.r.t. himself. His fingers at the moment of toss are midway between the floor and cciling, whose total height is 2 m. Displacement of coin when it hits the ground is x metre (in earth frame). Value of x is : (g = 10 m//s^(2))
