Calculate: Kinetic energy (K) depends on the mass and speed (v) of the object. The equation for kinetic energy is:
K = mv2
With Hill 1 set to 75 cm, click Play and allow the car to reach the bottom.
What is the final speed of the car, in meters per second?
What is the kinetic energy of the car, in joules? (Use the mass in kg.)
0.386 J
How does the car’s kinetic energy at the bottom of the hill compare to its potential energy at the top?

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?
