The y-component of a projectile’s velocity is 12.1 m/s. when the projectile once again passes by the height from which it was launched, what is the y-component of its velocity? impossible to calculate without knowing the x-component 0 m/s 12.1 m/s -12.1 m/s

Two friends are having a conversation. anna says a satellite in orbit is in freefall because the satellite keeps falling toward earth. tom says a satellite in orbit is not in freefall because the acceleration due to gravity is not 9.80 m/2 . who do you agree with and why?

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.)

What are the dimensions of the cross section that passes through the points a, f, g, and d?
