A light spring having a force constant of 125N/m is used to pull a 7.20kg 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 1.80m/s^2. By how much does the spring stretch if it pulls on the sled horizontallly? If the string stretches by the same amount but is pulling the sled at 30 degrees above the horizontal, what is the new acceleration?
