Question

A light spring having a force constant of 110  is used to pull a 15.0  sled on a horizontal frictionless ice rink. The sled has an acceleration of 1.60 ?
[2/27/12 9:41:56 PM] Matt Yeager: By how much does the spring stretch if it pulls on the sled at 29.0 above the horizontal?

There are no units here, it is impossible to work without units. On the second question, one has to know the spring constant.
