A rocket is launched from Cape Canaveral in Florida. The diagram depicts the forces acting on the rocket. As the hot burning gases push down, the rocket goes up. The rocket must reach escape velocity to leave Earth's gravity, and travel into space.

Final Velocity = 11,000 m/s

Initial Velocity = 0 m/s

Time = 500 s

Multiple Choice
