Momentum question

[whitestrat69]

1. The problem statement, all variables and given/known data
A man (mass 80kg) reaches the edge of a 20m cliff in his car (mass 1600kg) at a speed of 150km/hr. He drives off the edge without a change in velocity.

Calculate the speed at which he enters the water if he ejects from his car at 50km/yr just as the car reaches the water?

Show what you've done so far.

Also, the direction of ejection is not mentioned. That is crucial.

Hmm.....kilometres per year is an interesting unit.
