Problem Solving, write all your computations and always encircle your final answer. This is all about General Physics 1: Work - Kinetic Energy Theorem.

Work-Kinetic Energy Theorem Problem Solving 12. A woman pulls a sled with her son (total mass of 80 kg) with a force of 180 N angled at 20° from the horizontal. The woman is able to move the sled 5 m along the horizontal. How much work is being done by the woman? 13. A woman pulls a sled with her son (total mass of 80 kg) with a force of 180 N angled at 20° from the horizontal. The woman is able to move the sled 5 m along the horizontal. What is the sled's velocity after it has moved 5 m, assuming that it started from rest and there is no friction?
