Consider an elastic collision in one dimension that involvesobjects of mass 2.5kg and 4.5kg. The larger mass is initially atrest, and the smaller one has an initial velocity of 12 m/s. Find the final velocities of the two objects after the collision.
An ideal spring of negligible mass is 13.00 long when nothing is attached to it. When you hang a 3.00- weight from it, you measure its length to be 14.50 .If you wanted to store 10.0 of potential energy in this spring, what would be its total leng..

A uniform electric field of magnitude 300 V/m is directed in the positive x direction. A +10.0 µC charge moves from the origin to thepoint (x, y) = (20.0 cm, 50.0 cm). What was the change in the potential energy of this charge?
A block of weight 43.6 N is hanging from a rope. The tension from the rope is pulling upward on the block. The block is accelerating upward at a rate of 1.22 m/s^2. What is the magnitude of the tension in the rope?

A circular loop of wire lies in the plane of the paper. An increasing magnetic field points out of the paper. What is the direction of the induced current in the loop?
A hunter on a frozen, essentially frictionless pond uses a rifle that shoots 4.20 g bullets at 975 m/s. The mass of the hunter (including his gun) is 68.5 kg, and the hunter holds tight to the gun after firing it. a) Find the recoil velocity of the h..
