1. A glider on a low friction air truck has a thaws of 0 250 ke and is moving south at 9 900 m/s. A second glider has a mass of 0.500 ke and is moving north at 0.700 ifs. The gliders collide inclastically. Inimmediately after the collision, the velocity of the less massive glider is 0.300 m/s, north, and the velocity of the more massive glider is 0.100 m/s. north B. 0.100 m/s, south C. 1.00 m/s. north D. 1.00 m/s. south Use the following information to answer question 2. A student sits on a skateboard and holds onto a fire extinguisher. The student aims the nozzle of the fire extinguisher straight backward and releases the propellant. The student and skateboard do not move forward. 2. Based on the results of this event, the student-fire-extinguisher system can be classified as i . This means that the application of conservation of momentum to analyze the system is ii The statements above are completed by the information in row Row i ii A. isolated valid B. isolated invalid C. non-isolated valid D. non-isolated invalid
