Homework Statement
The entire problem is in the attached picture. I have been checking and double checking for about an hour, found solutions online which agree with my solution, but I cannot find any answer beside 3.697 m/s which is marked wrong by the computer program.
Homework Equations
Is the homework program wrong or am I somehow missing something?
df/dt = (2xy)/(2(x^2+y^2xy)^(1/2))(dx/dt) + (2yx)/(2*(x^2+y^2 xy)^(1/2))(dy/dt)
The Attempt at a Solution
All of this works out to 3.697. I have tried rounding, leaving the answer as postive, nothing seems to work. Very frustrated.
