An object moves with constant acceleration 4.00 m/s^2 and over a time interval reaches a final velocity of 12.0 m/s.(a) If its initial velocity is 6.00 m/s, what is its displacement during the time interval?(b) What is the distance it travels during this interval?(c) If its initial velocity is -6.00 m/s what is its displacement during the time interval?(d) What is the total distance it travels during the interval in part (c)?
Two rigid rods are oriented parallel to each other and to the ground. The rods carry the same current in the same direction. The length of each rod is 0.90m, and the mass of each is 0.078 kg. One rod is held in place above the ground, while other flo..
