    Derivative with e and Definte integral

    1. Find y' if xey + 1 = xy The attempt at a solution I separated the y: y= ey + 1/x After deriviation: y' = e2(dy/dx) -1/(x2) Is this correct? If so, how do solve after since this question is m/c which one of choices is (y-ey)/ (xey-1), though it could be none of above. 2. Find...

    Astronomic gravitation problems

    1. If the INternational space station has an orbital velocity of 9,000 m/s. find the time (in minutes) it takes to make one complete orbit. Relevant equations F = mv2/ R = m4[pi]2R / T2 The attempt at a solution Is this the way to solve for T? Do I use Earth mass and Earth R b/c that...

    Conservation momentum questions help

    1. A 1.0 kg mass moving with a velocity v m/s strikes a stationary mass (assume no frictional losses). a. Is it possible for both masses to move in the same direction and at the same speed after the collision? If so, find the value of the stationary mass. b. Is it possible for both masses to...
