During a neighborhood baseball game in a vacant lot, a particularly wild hit sends a 144 g baseball crashing through the pane of a second-floor window in a nearby building. The ball strikes the glass at 10.9 m/s, shatters the glass as it passes through, and leaves the window at 8.93 m/s with no change of direction. Calculate the magnitude of the impulse J that the glass imparts to the baseball. If the baseball is in contact with the glass for a time At of 10.6 ms, what is the magnitude of the average force Face of the glass on the ball? Determine the velocity of block A after the collision. Determine the velocity of block B after the collision. J- Frang A 10.0-kg block of ice is sliding due east at 9.00 m/s when it collides elastically with a 6.00-kg block of ice that is sliding in the same direction at 4.00 m/s. Define the positive direction as pointing due cast, the 10.0-kg block as block A, and the 6.00-kg block as block B. What speed (in miles per hour) was car A traveling just before the collision? (This problem uses English units because they would be used in a U.S. legal proceeding.) N.S 3- N m/s due cast Our- You have been called to testify as an expert witness in a trial involving a head-on collision. Car A weighs 1515 lb and was traveling castward. Car B weighs 1125 lb and was traveling westward at 43.0 mph. The cars locked bumpers and slid castward with their wheels locked for 21.5 ft before stopping. You have measured the coefficient of kinetic friction between the tires and the pavement to he 0.750. m/s duc cast mph
