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.

Two stationary positive point charges, charge 1 of magnitude 3.45 nC and charge 2 of magnitude 1.50 nC, are separated by a distance of 52 cm. An electron is released from rest at the point midway between the two charges, and it moves along the lin..
A person fishing from a pier observes that five wave crests pass by in 7.4 s and estimates the distance between two successive crests to be 4.3 m. The timing starts with the first crest and ends with the fifth. What is the speed of the wave? m/s
A ball is held on an incline at the height of 72 cm. it is then released so that the ball rolls down the incline. At the bottom of the incline there is a loop where the ball rolls around in. If the loop is 62 cm high at its highest point what is the ..
