Explanation: Electrostatic force is directly related to the charge of each object. So if the charge of one object is doubled, then the force will become two times greater.
0.31m/s
Explanation:
Given parameters:
Time of travel = 4hrs = 4 x 60 x 60 = 14400s
Displacement = 4400m due west
Unknown:
Velocity = ?
Solution:
Velocity is defined as the displacement per unit of time. It is expressed in m/s or km/hr:
Velocity = 
Velocity =
= 0.31m/s

Because the act of braking is an example of negative acceleration.
Example: if the rate of braking was say 2 meters per second^2, and the starting velocity was 10 m/s, it would take 5 seconds to come to a stop(during those 5 seconds you would still be moving).
