3. [0/1 Points] + Additional Materials + DETAILS Train cars are coupled together by being bumped into one another. Suppose two loaded train cars are moving toward one another, the first having a mass of 140,000 kg and a velocity of 0.300 m/s, and the second having a mass of 105,000 kg and a velocity of -0.120 m/s. (The minus indicates direction of motion.) What is their final velocity (in m/s)? 0.10690 X m/s Reading 4. [-/1 Points] DETAILS Additional Materials puck goalle PREVIOUS ANSWERS PRACTICE ANOTHER A 1.40 kg falcon catches a 0.170 kg dove from behind in midair. What is their velocity (in m/s) after impact if the falcon's velocity is initially 26.0 m/s and the dove's velocity is 3.00 m/s in the same direction? (Enter the magnitude.) m/s Reading OSCOLPHYS2016 8.3.P.023. OSCOLPHYS2016 8.3.P.027. PREVIOUS ANSWERS MY NOTES ASK YOUR TEACHER x m/s m/s 5. [0/2 Points] DETAILS A 66.0 kg ice hockey goalie, originally at rest, catches a 0.150 kg hockey puck slapped at him at a velocity of 22.0 m/s. Suppose the goalie and the ice puck have an elastic collision and the puck is reflected back in the direction from which it came. What would their final velocities (in m/s) be in this case? (Assume the original direction of the ice puck toward the goalie is in the positive direction. Indicate the direction with the sign of your answer.) 0.120937 OSCOLPHYS2016 8.4.P.030.
