60 kg is not the weight, it is the mass. Also, the velocity is 50 m/s, not 50 meters.
To convert mass in kg to weight in Newtons, multiply by g = 9.8 m/s^2. you answer to the problem will be in Joules/s (same as Watts)
A 60 kg skydiver moving at terminal speed falls 50m in 1 s. What power is the skydiver expending on the air?
This what I got so far:
powerloss=weight * velocity
powerloss=60kg *50m
powerloss=3000 (but I don't know the units)

W=mg =(60kg)(10m/s^2)=600N
So, P=F×d/t=(600N)(50m)/(1s)=30,000J/s=30kW
So, P=F×d/t=(600N)(50m)/(1s)=30,000J/s=30kW
