Physics question

1. A simple harmonic oscillator has a total energy of E. a.) Determine the kinetic and potential energies when the displacement is one half the amplitude. B.)For what value of the displacement does the kinetic energy equal the potential energy? 2.A 5.00g bullet moving with an initial speed of 400m/s is fired into and passes through a 1.00kg block. The block, initially at rest on a frictionless horixontal surface, is connected to a spring with a spring constant of 900N/m. If the block moves 5.00cm to the right after impact, find a)the speed at which the bullet emerges from the block and b) the mechanical energy lost in the collision. 3.Assume that a hole is drilled through the cent... click for more

Fluids

What is the ABSOLUTE pressure on the bottom of Archimede's bathtub if the dimensions of the tub are 3m long by 1.2m wide by 0.8m high? Assume that the tub is filled to the top with water and Archimedes hasn't gotten into the tub yet? What is the force on the bottom of Archimedes's baththub?
