Narrative:

I was captain in the right seat. I was told by approach to maintain 170 kts until FAF. Pilot flying was having difficulty slowing the aircraft down and was still above 200 kts after the FAF on the ILS 35R at okc. Was unaware that there was an aircraft on the runway. Weather was MVFR with 2 miles visibility reporting with 400 scattered; 1200 scattered; 8000 overcast. It was almost night time. On about a 1 mile [final]; tower tells us to go around as the aircraft on the runway began its takeoff roll. We were over the runway at about 400 ft when we believe the instructions from the tower told us to turn right. We said; 'say again.' we believe tower said '[call sign] turn right.' not really understanding what the tower wanted us to do; we ask; 'what do you want us to do?' then finally I believe another voice came over and said 'turn right to 050 and climb to 3000 feet.'there was never any threat of a midair but the instructions from the tower were initially not understood and of no help. A significant issue could have occurred if we would have continued runway heading with the aircraft taking off below us. One of the main issues of us getting into this situation was the inability of the pilot flying to slow our aircraft down; however we were never told that there was an aircraft on the runway preparing for takeoff; or the need to slow our aircraft down by the tower because an aircraft was on the runway preparing for takeoff.

Title: Falcon 2000 Captain is instructed to go-around by the Tower when the flying First Officer is unable to slow sufficiently for an aircraft in position on the runway. The DA2000 flight crew is instructed to go-around at about the same time the aircraft on the runway begins its takeoff roll; resulting in a NMAC. The Tower initially instructed the crew to turn right without giving a heading or an altitude which delayed their compliance.
