Discussion :: KOP: Impulse and Momentum - General Questions (Q.No.4)


In cases of emergency, the gas actuator can be 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 ofthe cylinder, A, to move B and the floor is = 0.5, determine the impulse that the actuator must impart to B.

[A]. Imp = 147.2 N-s
[B]. Imp = 132.2 N-s
[C]. Imp = 15.00 N-s
[D]. Imp = 162.2 N-s

Answer: Option D
