A light spring having a spring constant of 125 N/m is used to pull a 9.50 kg sled on a horizontal frictionless ice rink. The coefficient of kinetic friction between the sled and the ice is 0.200. If the sled has an acceleration of 2.00 m/s2, by how much does the spring stretch if it pulls on the sled: at 30.0° above the horizontal?
