A ball is hanging from a long string that is tied to the ceiling of a train car traveling eastward on horizontal tracks. An observer inside the train car sees the ball hang motionless. Part A Draw a clearly labeled free-body diagram for the ball if the train has a uniform velocity. Draw the force vectors with their tails at the dot. (Black vector is the sum of the vectors in my diagram.) Part B Draw a clearly labeled free-body diagram for the ball if the train is speeding up uniformly. Draw the force vectors with their tails at the dot. (Black vector is the sum of the vectors in my diagram.)
