In a typical Hollywood movie stunt, a person jumps off a building and lands on a cushion to safely stop. Imagine using an electric interaction to stop a charged object instead. Consider a 90 kg object wit a charge of 0.8C that is dropped (from rest) 10 m from the ground (between two plates that are connected with a battery).
How much voltage should the battery have to stop the object as it reaches the ground? Also write in how the battery should be connected between the plates.
