A light spring having a force constant of 149is used to pull a 7.50 sled on a horizontal ice rink. The coefficient of kinetic friction between the sled and the ice is 0.200. The sled has an acceleration of 2.34. By how much does the spring stretch if it pulls on the sled horizontally? By how much does the spring stretch if it pulls on the sled at 30.0 above the horizontal?
