A 2 kg mass is oscillating on a spring that has a spring constant of 40 N/m. The speed of the mass is 1.5 m/s when it passes through the equilibrium position.

a. What is the period of the oscillation?

b. What is the total energy of the system?

c. What is the maximum displacement (amplitude) of the oscillator?

d. What is the speed of the mass when its displacement is 0.2 m?

e. If t=0 seconds when the mass is at its maximum displacement, what is its displacement atte12 seconds?

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?
