Aside from pulley ratios, friction, etc. The fastest possible time based on physics, alone is...

The work done to lift 2000 lb, 20 feet = distance * mass * g

Horsepower is a unit of power, or energy/time
10 H.P. is equivalent to 7.457 kiloWatts (kJ/s)

2000 lb. force is equivalent to 907.2 Newtons

That should get you going.

There are to many unknows on the question. What is the gear ration, is there a vfd and if so what is the ramp time? What is the diameter of the pullys used, what is the cable diameter?
