3) An 8 kg sled is at rest on a horizontal road. The coefficient of kinetic friction between the sled and the road is 0.4. The sled is pulled a distance of 3 m by a force of 40 N applied to the sled at an angle of 30 degree. a) Find the work done by the applied force. b) Find the work done by friction. c) Find the change in kinetic energy of the sled. d) Find the speed of the sled after it has traveled 3 m.

(a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
