Extracted text: Solve the following exercise in two different ways: 1) Using the principle of Work and Energy. 2) Using Newton's Second Law. Compare the results obtained, and explain any possible differences. The 300-lb car has an initial speed of 9 ft/s at point A as shown in the figure, after which a force of 110 lb is applied to the end of the pulley. Determine the speed of the cart at point B. 110 lb UA =9 ft/sec 300 lb 10 B 5n A 12
