Narrative:

Just prior to push back; takeoff data was rejected due to gw (gross weight) greater than tow (takeoff weight). New takeoff data was requested with an incorrect takeoff weight (tow). A tow of 106.7 was entered vs. The correct tow of 160.7. During taxi; before takeoff checklist was accomplished; incorrect weight was not caught by crew. During takeoff; pilot flying rotated at vr (takeoff rotation speed) on the FMC (flight management computer) takeoff page and speed tape. Rotation was recorded at 11.4' and tail strike occurred. On climb out airspeed was low; stall warning activated; pm (pilot monitoring) called airspeed; pitch was lowered; aircraft accelerated and departure was continued. All altitude constraints and SID (standard instrument departure) routing were met. During climb out flight attendants contacted cockpit and confirmed a tail strike. Crew continued departure; cleared terrain; completed QRH (quick reference handbook) tail strike checklist and coordinated descent from 19;000 feet with ATC (air traffic control). Company/dispatch was notified. Aircraft held; burning fuel to reduce to landing weight. Aircraft landed without further incident.

Title: B737 flight crew reported being provided incorrect takeoff weight data resulting in tail-strike on takeoff.

Narrative: Just prior to push back; takeoff data was rejected due to GW (Gross Weight) greater than TOW (Takeoff Weight). New takeoff data was requested with an incorrect takeoff weight (TOW). A TOW of 106.7 was entered vs. the correct TOW of 160.7. During taxi; before takeoff checklist was accomplished; incorrect weight was not caught by crew. During takeoff; pilot flying rotated at VR (Takeoff Rotation Speed) on the FMC (Flight Management Computer) takeoff page and speed tape. Rotation was recorded at 11.4' and tail strike occurred. On climb out airspeed was low; stall warning activated; PM (Pilot Monitoring) called airspeed; pitch was lowered; aircraft accelerated and departure was continued. All altitude constraints and SID (Standard Instrument Departure) routing were met. During climb out flight attendants contacted cockpit and confirmed a tail strike. Crew continued departure; cleared terrain; completed QRH (Quick Reference Handbook) tail strike checklist and coordinated descent from 19;000 feet with ATC (Air Traffic control).
