Combine Part 2 (Newtons second law of motion proving W=K(B)-K(A)) and the Fundamental Theorem for Line Integrals to prove the Law of Conservation of Energy. You must point out at which step you use the fundamental theorem for line integral.
2. (4 points) Use Newton's Second Law of Motion to prove: The work down by a force field F along a path Cis equal to the change in kinetic energy at the endpoints ofC. i.e. Prove: W- K(B)-K(A) rla) A nihal point rlb)B terminal Pant Accordnq to Newtons 2nd Law: rmt) a. r'tb ã mv(+): Kinetic enerqy So, 3. (4 points) Combine part 2 and the Fundamental Theorem for Line Integrals (Theorem 2 on page 925) to prove the Law of Conservation of Energy. You must point out at which step you use the fundamental theorem for line integral.
