But how how would K is equal to 1/225?

A parachutist is falling with speed 176 ft/s when his parachute opens. If the air resistance is Wv2/225 lb where W is the total weight of the man and the parachute and v is in ft/s, find his speed as a function of time after the parachute opens.

I have no any ideas. But in reference with Differential Equation 7th edition by rainville and bedient. It's under on ADDITIONAL TOPIC IN FIRST ORDER DIFF. EQUATION

solve n(9m²+18m-mn²-n²)dm + m(9m+9mn-3n²-n³)dn = 0

How is that happen? What does implicit differentiation implies? - - - Updated - - - The arbitrary constant is'nt eliminated too.

Re: Any one who can solve this? Anyone pleasee? I need your help with this eliminating arbitrary constant. y= 8a³/ (x²+4a²)

Re: Any one who can solve this? Eliminate the arbitrary constant.

y= 8a³ / x²+4a²
