1) A man is pulling his child on a sled with a force of 100.0 N at an angle of 25° above the ground. The mass of the child and sled together are 68.0 kg. The force of kinetic friction acting between the sled and the snowy surface is 26.0 N. The sled is pulled a displacement of 23.0 meters to the right. IA 101

a. Determine the work done on the sled by the man's applied force. [A 2] Determine the work done on the sled by the force of friction. [A 2] Determine the work done on the sled by the normal force. [A 1] Determine the net work done on the sled. [A 1] If the sled was initially at rest, then calculate the speed of the sled after the 23.0 metres. Use energy and work to solve. [A 3]
