A person hits a golf ball with a speed of 3.0 x 10' m/s at an angle of 40.0° to the horizontal. What is the total time that the ball is in the air?

Alfred pushes on a heavy box, but cannot move it. the box has a lot of inertia motion friction gravity

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.)
