Two small metallic spheres are fired at each other from an initial separation distance of 21.3 cm. The sphere coming from the left has a mass of 12.5 g, a charge of 2.70 μC, and an initial speed of 7.30 m/s. The sphere coming from the right has a mass of 23.2 g, a charge of 6.50 μC, and an initial speed of 5.20 m/s. ) What is the original total energy (in J) of the system? b) Determine the separation distance (in cm) at which the two spheres will come to a stop before starting to move away from each other

2. What is the trigonometrical relationship between vector and its' horizontal and vertical components?

the vector some of 80 N in the -x direction and 30 N at an angle of 53 with the +x axis is   ......  N

Determine F1 and the angle of Theta. If the magnitude of the resultant force acting on the eyebolt is 800N and its direction measured clockwise from the positive x axis theta=30.
