One particle has a mass of 4.41 x 10-3 kg and a charge of +6.92 ?C. A second particle has a mass of 6.52 x 10-3 kg and the same charge. The two particles are initially held in place and then released. The particles fly apart, and when the separation between them is 0.171 m, the speed of the 4.41 x 10-3 kg-particle is 194 m/s. Find the initial separation between the particles.
A father racing his son has 1/2 the kinetic energy of the son, who has 1/3 the mass of the father, What are the original speeds of (b) the son
The same voltage is applied between the plates of two different capacitors. When used with capacitor A, this voltage causes the capacitor to store 12 C of charge and 6.1 x10-5 J of energy.
A (smooth) rope of length L and mass m is placed above a hole in a table. One end of the rope falls through the hole, Find the mechanical energy lost from the rope as the end of the rope leaves the table

A fireman, 25.6 m away from a burning building, directs a stream of water from a ground level fire hose at an angle of 39.5° above the horizontal
Smoke particles in the air typically have masses of the order of 10 to 16 kg. The Brownian motion (rapid, irregular movement) of these particles, resulting from collisions with air molecules, can be observed with microscope.
Determine out the work completed to move the particle from x = 0 to x_3 = 10.5 m graphically by determining the area under the F_x vs. x graph.
At time t = 0, the hockey puck is sent sliding over a frozen lake, directly into a strong wind. Gives the velocity v of the puck versus time as puck moves along a single axis. (The time axis is marked in increments of 0.25 s.) At t = 2.8 s, what i..
