Two identical spheres each having charge Q =-11 nC and mass mOF 10 milligrams are held fixed at their positions 5.0 cm apart. A particle with charge q-+1.0 nC and mass mo-0.40 milligrams is released from rest at a position 5.0 cm from each sphere (so initially the particle and the spheres form an equilateral triangle). Find the speed of the positively charged particle when it passes a point exactly in between the two spheres. (k - 9.0 x 109...

1. A firework (small rocket) whose shell has a mass of m 12kg was initially on the ground before being launched to a height of 100m above the ground at which point its horizontal displacement from its starting position is 17.6m. At this location its speed is 68m/s and it's at an angle relative to (and above) the horizontal of 80 as depicted in the diagram below. Once it reaches this height it goes off and its shell splits into...
