7. A 0.90 kg falcon is diving at 28.0 m/s at a downward angle of 35° (figure 3). It catches a 0.325 kg dove from behind in midair. What is their combined velocity after impact if the dove’s initial
velocity was 7.00 m/s directed horizontally?

Acar accelerates from 5.0 m/s to to 11 m/s at a rate of 3.0 m/s^2. how far does it travel while accelerating? 20m 117m 43m 16m

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.)

Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.
