Problem 29E

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. Draw a clearly labeled free-body diagram for the ball if (a) the train has a uniform velocity and (b) the train is speeding up uniformly. Is the net force on the ball zero in either case? Explain.

Step-by-Step Solution:

Solution 29E Step 1: A ball is hanging from a long string that is tied to the ceiling of a train car traveling eastward on horizontal tracks. Step 2: Problem (1) To find net force on the ball, when velocity is constant. If the train moves with uniform velocity, there will be no net force on the ball. The only force due to acceleration due to gravity is balanced by the tension on the thread.
