A 10-kg mass and a 5-kg mass are connected by a string. The string is hung taut over a pulley such that the 5-kg mass is resting on the ground, and the 10-kg mass is 0.35m above the ground. The 10-kg mass is released from rest, causing it to fall while the 5.0-kg mass is pulled upward. What is the common speed of the two masses at the moment just before the 10-kg mass reaches the ground
