Two positively charged objects are separated by a large distance. One of the positively charged objects is replaced by a negatively charged object, and the two
objects are moved closer to each other.
Which of the following occurs in this situation?
a.
The attractive force becomes a repulsive force, which increases as the objects move closer
together.

B.
The repulsive force becomes an attractive force, which increases as the objects move closer to
each other.
C.
The attractive force becomes a repulsive force, which decreases as the objects move closer to
each other.
D.
The repulsive force becomes an attract
creases as the objects move closer to
each other.

Jason and mia are both running in a race. as they approach the finish line, you being the physicist that you are decide to time how long it takes them to reach the end of the race. when you start your stop watch (you can take this as time t = 0 s) you notice that mia is an unknown distance d ahead of jason and both are moving with the same initial velocity v_0. you also notice that jason is accelerating at a constant rate of a_j, while mia is deaccelerating at a constant rate of -a_m. jason and mia meet each other for the first time at time t = t_1. at this time (t = t_1) jason's velocity is two times that of mia's velocity, meaning v_j (t_1) = 2v_m (t_1). a) draw the position vs. time graph describing mia's and jason's motion from time t = 0 to time t = t_1. clearly label your axes and initial conditions on your graph. b) draw the velocity vs. time graph describing mia and jason's motion from time t = 0s to time t = t_1. clearly label your axes and initial conditions on your graph. c) how long from when the stop watch was started at t = 0s did it take mia and jason to meet? express your answer in terms of know quantities v_0, a_m, and a_j. d) when the stop watch started at time t = 0s, how far apart, d, were mia and jason? express your answer in terms of know quantities v_0, a_m, and a_j.
