Vertical 1D Motion Problem

BELLWORK!!

- A Moon rock ON THE MOON is thrown upward with velocity of 7 m/s. After 7 s, it has a downward velocity of 4 m/s. What is the acceleration due to gravity on the Moon? How high above the starting point did the rock go before it began to fall?

- What is the acceleration due to gravity on the Moon?
- How high above the starting point did the rock go before it began to fall?

- vo = + 7 m/s ( or upwards )
- vf = -4 m/s ( or downwards )
- Time interval of 7 sec ( t = 7 s )

NOW HAVE ADDITIONAL INFO ( value for g )

- What are you asked to find?
- Height of rock ( above initial position ) before rock falls

- Any more info from this?
