A 1.20 kg mass on a horizontal spring oscillates on a frictionless surface with a displacement as a function of time given by x(t) = 0.075cos(4.16t – 2.45). (Units are standard units.) a.) Find the time for one complete vibration. b.) Find the force constant of the spring. c.) Find the maximum force on the mass. d.) Find the maximum speed of the mass. e.) Find the position, speed and acceleration of the mass at t = 1.00 s. f.) Find the total energy of the oscillating spring.
Compute the magnitude and direction of the total gravitational force exerted on one sphere by the other three.
A certain kind of glass has an index of refraction of 1.655 for blue light of wavelength 430 nm and an index of 1.62 for red light of wavelength 680 nm. A beam containing these two colors is incident at an angle of 42.22 degrees on a piece of this g..
