A ball is dropped from rest from the top of a building. Two motion detectors which are positioned outside of two different windows, one above the other, record the velocities of -15.5 m/s and -17.2 m/s as the ball goes past them. (no air resistance) a. How far apart are the motion sensors mounted? b. How far from the top motion sensor is the top of the building where the ball was released? c. If the second motion sensor can...

A rock is dropped from the top of a vertical cliff and takes 3.00 s to reach the ground below the cliff. A secon rock is thrown vertically from the cliff, and it takes this rock 2.00 s to reach the ground below the cliff from the time it is released. With what velocity was the second rock thrown, assuming no air resistance? Select one: a. 5.51 m/s downward , b. 4.76 m/s downward X O c. 12.3 m/s downward...
