On May 20th we held the following competition and Christoper Flanagan won with an answer of 2.95 meters.

"JURBAN will be giving away a $15 cash prize to the first student (K-12), to determine the max height our air bag landing system can fall from (starting with zero velocity), and the hit lunar surface at less than 3.1 m/s Hint: constant acceleration equations."

From 60 Degrees

The JURBAN team is doing it again and here is your chance to win $15, if you are in grade K-12. This time you need to determine the number of times our airbag system will bounce on the Moon before coming to rest.

Hints:
• ♥ First impact is at 3.1 meters per second at an angle of 60 degrees from the lunar surface
• ♥ A bounce height of less than 2.54 cm is considered at rest
• ♥ A horizontal velocity of less than 0.0089 meters per second is considered at rest
• ♥ Use a coefficient of restitution value of 0.62

Please email us at JURBAN@solarsystemexpress.com to submit your answer and for problem clarification.

We will announce the winner and give weekly hints (on Fridays) via our Facebook Page**, so please ”like” us. See the following Youtube video for the general mission timeline, http://www.youtube.com/watch?v=IvGUxAwDeUg
