Problem 4: (use energy methods) When s = 0, the spring on the firing mechanism is unstretched. If the spring is pulled back to s = 100mm and released. The mass of the ball is 0.3kg. Determine: 1. The speed of the ball as it leaves the spring and is about to start moving on the circular track. 2. The maximum angle θ the ball will travel without loosing contact with the circular track. Assume all contact surfaces to be s

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?
