In case of emergency, the gas actuator is used to move a 75-kg block B by exploding a charge C near a pressurized cylinder of negligible mass. As a result of the explosion, the cylinder fractures and the released gas forces the front part of the cylinder, A, to move B forward, giving it a speed of 200 mm>s in 0.4 s. If the coefficient of kinetic friction between B and the floor is k = 0.5, determine the impulse that the actuator imparts to B.
