Be sure you understand why a pendulum in equilibrium hanging in a car that is accelerating forward tilts backward, and then consider the following: a helium balloon is anchored by a massless string to the floor of a car that is accelerating forward with acceleration a. explain clearly why the balloon tends to tilt forward and find its angle of tilt in equilibrium. [hint: helium balloons float because of the buoyant archimedean force, which results from a pressure gradient in the air. what is the relation between the directions of the gravitational field and the buoyant force? ]

The average time that it takes for the car to travel the first 0.25m is s. the average time to travel just between 0.25 m and 0.50 m is s. given the time taken to travel the second 0.25 m section, the velocity would be m/s.
