Five persons A, B, C, D & E are pulling a cart of mass 100kg on a smooth surface and cart is moving with acceleration 3 m//s^(2) in east direction. When person 'A' stops pulling, it moves with acceleration Im/s in the west direction. When person 'B' stops pulling, it moves with acceleration 24m//s^(-2) in the north direction. The magnitude of acceleration of the cart when only A & B pull the cart keeping their directions same as the old direction is
