Vertical 1D Motion Problem

2
On the Moon 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?

4
Given Information v o = + 7 m/s ( or upwards ) v f = -4 m/s ( or downwards ) Time interval of 7 sec ( t = 7 s )

10
Part B – Appropriate Formula 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?

11
Part B – Appropriate Formula 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? – Final velocity at top of path is zero

13
Part B – Substitute Values

14
Part B – Solve

15
Part B – Solve This value should actually be 1.57 m/s 2 since you do not want to round—IN ANY PROBLEM, EVEN IF YOU ARE USING THE ANSWER FROM A PREVIOUS ONE— UNTIL THE VERY END

16
Part B – Without Sig Figs?
