During a neighborhood baseball game in a vacant lot, a particularly wild hit sends a 142 g baseball crashing through the pane of a second-floor window in a nearby building. The ball strikes the glass at 10.5 m/s, shatters the glass as it passes through, and leaves the window at 8.71 m/s with no change of direction. What is the direction of the impulse that the glass imparts to the baseball? O opposite the direction of the ball's motion neither of these the direction of the ball's motion Calculate the magnitude of this impulse, a positive number. magnitude of impulse: N-s The ball is in contact with the glass for 10.1 ms as it passes through. Find the magnitude of the average force of the glass on the ball, a positive number. magnitude of average force: N
A 5.8 x 10 kg train car at rest is struck from behind by a second train car, traveling at 2.6 m/s. The collision is completely inelastic so the cars stick together. The mass of the second car is 7.4 x 10¹ kg. What is the velocity of the joined trains cars immediately after the collision? m/s Round your answer to the tenths place.
