Find the acceleration of a vehicle that has a momentum of 50 kg*m/s and a velocity of 5 m/s after it experiences a force of 10 N? Describe as best you can the equation or equations needed and how you utilized them to calculate your answer.

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
