    Derived equation initial speed

    Finward = Fg m1 v^2 / r = Gm1m2/r v^2 = Gm2/r v = (square root of) Gm2/r G= gravitational constant = 6.67x10^-11 m2= mass of Earth = 5.98x10^24 r= radius of Earth + altitude of satellite above Earth = 6.37x10^6 + 1000 ? If everything else is right, would this equation give me...

    Derived equation initial speed

    Finward = Fg m1 v^2 / r = Gm1m2/r v^2 = Gm2/r v = (square root of) Gm2/r v = (square root of) (6.67x10^-11)(5.98x10^24)/(1000/2) v = (square root of) (6.67x10^-11)(5.98x10^24)/500 v = (square root of) 7.977... I didn't round of 7.977...on my calculator; I saved the whole number and...

    How to find acceleration. With only Force of friction?

    In the first part, the velocity is constant, so his acceleration is -9.8 m/s ^ 2? So from the first part, can you calculate the mass of the person? F=ma m=F/a m=800 N / -9.81 m/s ^ 2 m= 81.55 m/s ^ 2 In the second part, he is being slowed by an acceleration (or deceleration if you like)...
