A2.0x10^3kg car accelerate from rest under the actions of two forces. one is a forward force of 1140n provided by traction between the wheels and the road. the other is a 950n resistive force due to frictional forces. use the work-kinetic energy theorem to determine how far the car must travel for its speed to reach 2.0m/s.

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?

What organization and environment is described above?

A14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.
