Calculate the average potential energy for the v=1 state of a harmonic oscillator. Use the substitutions for α and ω from your class notes to simplify your answer.
An alpha particle (helium nucleus, charge 2e) starts from rest and travels a distance of 1.88 cm under the influence of a uniform electric field of magnitude 12.2 kV/m
His velocity at the start of the final mile was about +16.58 m/s. The acceleration, although small, was very important to his victory. To assess its effect, determine the difference between the time he would have taken to run the final mile at a c..
Three identical conducting spheres initially have following charges: sphere A, 5Q; sphere B, -7Q; and sphere C, 0. Spheres A and B is fixed in place, with a center-to-center separation that is much larger than the spheres.
What is the centripetal force that would be required to keep a 4.0 kg mass moving in a horizontal circle with a radius of 0.80 meters at a speed of 6.0 meters/second?

Two metal balls A and B of negligible radius, connected by a taut nonconducting thread of length 2.90 m, are floating at rest on Space Station Freedom between two metal bulkheads.
The cord between the pouch and the person's hand has negligible mass and will break when the tension in the cord is 33.0 N or more. Assume the sling thrower could gradually increase the speed of the stone.
A convex spherical mirror, whose focal length has a magnitude of18.8cm, is to form an image11.2cm behind the mirror. Where should the object be placed? What is the magnification of the mirror?
The mass mi moves on a smooth horizontal plane. m2 moves vertically under the force of gravity and the spring. Using polar coordinates r, θ for mi, l for m2, and taking b for the total length of the string plus the unstretched length of the spring..
