Five persons A, B, C, D & E are pulling a cart of mass 100kg on a smooth surface and cart is moving with acceleration 3m//s^2 in east direction. When person A' stops pulling, it moves with acceleration 1m//s^2in the west direction. When person 'B' stops pulling, it moves with accele-ration 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
