Billy pulls а 10.0 kg sled аcrоss а level snоw-cоvered surface. He applies a constant force of 10.0 N at an angle of 30.0° above the horizontal, pulling the sled to the left. The coefficient of kinetic friction between the sled and the snow is 0.50. The sled moves a horizontal distance of 10.0 m. Exam 2 - Q12.pnga. Calculate the work done by the applied force. b. Calculate the work done by gravity c. Calculate the work done by friction. d. Calculate the work done by the normal force. e. Find the change in the kinetic energy of the crate.
