A95 kg fullback is running at 4.0 m/s to the east and is stopped in 0.75 s by a head on tackle by a linebacker heading due west. calculate the original momentum of the fullback, the impulse exerted on the fullback, the impulse exerted on the linebacker, and the average force exerted on the linebacker

The goal of this experiment was to answer the question, "how does diffraction occur? " suppose you formulated this alternate hypothesis: if the gap width is increased while keeping wavelength constant, then the observed diffraction will decrease because the less the ratio between wavelength and gap width is, the smaller the observed diffraction angle will be.to test this hypothesis, you would change the  gap widthdiffraction anglewavelength  and observe the  gap widthdiffraction anglewavelength  in the system.therefore, the independent variable would be the  gap widthdiffraction anglewavelength  and the dependent variable would be the  gap widthdiffraction anglewavelength.
