A man and his bike are 95 kg. His instantaneous speed at one point is 14m/s. The next time his speed is checked he is going 28m/s. If the second speed was taken 7 seconds later, what force must the man have given his bike to change the speed? What was the bicyclist’s final momentum?

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?
