You are on the last run of the historic Orient Express train in 1939 traveling from Paris toIstanbul.Somewhere between Belgrade and Sofia, the train ominously starts accelerating inthe reverse direction—which we will call the negativexdirection. TheMAGNITUDEof thisacceleration isatr. The train is on aSTRAIGHT, level line of track. NeglectAIR DRAG.a) Inside the train car a projectile is launched in the positivexdirection (i.e., in the forwarddirection).What is the horizontal accelerationRELATIVEto the train car in termsof knowns?
