Ajet with mass m = 8 × 104 kg jet accelerates down the runway for takeoff at 1.5 m/s2.
i have found out so far
1) net horizontal force(takeoff) = 12
2)net vertical force(takeoff) = 0
once off the ground, the plane climbs upward for 20 seconds. during this time, the vertical speed increases from zero to 20 m/s, while the horizontal speed increases from 80 m/s to 96 m/s.
3)what is the net horizontal force on the airplane as it climbs upward = 64000
i need
4) what is the net vertical force on the airplane as it climbs upward?

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.)

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.

Which lists correctly orders nuclear reactions from most radioactive waste generated to least waste generated within a given period of time? o a. radioactive decay, nuclear fission, nuclear fusion o b. radioactive decay, nuclear fusion, nuclear fission o c. nuclear fusion, nuclear fission, radioactive decay o d. nuclear fission, nuclear fusion, radioactive decay
