Moving a mass for ten seconds

[sciencegeek100]

this is a disscusion for the task to move a mass for ten seconds or forty seconds for a bonus.

- motor turns and pulls string with nail that sets off a mousetrap

One thing I learned from competetion is that the string does not count as a mass, something has to be attatched to it for it to count.
Other ideas on this...

mine gets the boonus and has 95% perfect accuracy, c u at nats

Can this task be combined with the golf ball movement?

This is my first year doing this event in Division C (I did it in Division B, but that's a whole different ballgame). I was thinking having a motor/string method pull the golf ball slowly up 30 cm.

To be honest, it seems like a lot of these tasks can be combined in order to simplify the machine's design and construction....

all separate, and any order but the first/last steps as said in rules
