The world’s fastest warship belongs to the united states navy. this vessel, which floats on a cushion of air, suppose that during a training exercise the ship accelerates +2.67 m/s2, so that after 15.0 s its displacement is +6.00 × 102 m.

assume that the ship moves in a straight line.

calculate the ships final velocity after the acceleration.

What is the rate of 12 liters of water moving through a water hose in 4.0 minutes?

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?

The brightest star in the night sky in the northern hemisphere is sirius. its distance from earth is estimated to be 8.7 light years. a light year is the distance light travels in one year. light travels at a speed of 3.00 × 108 m/s. calculate the distance from earth to sirius in miles.
