As part of her role, Jen is responsible for unloading some of the material that is transferred using a spool her team has put together (see the figure below). Each block of material (block A) is 20 kg, and the spool has a mass of 50 kg and a radius of gyration of kO = 0.280 m. Help Jen calculate the velocity of block A after it descends a total of 0.5 m from rest.

Jen is a project manager at a construction site with a very low ratio of female to male workers. As one of the very few women in this position, she aims to recruit more women into this field. She has therefore, decided to let others know about the details of her job, and inform her colleagues that her job is not physically demanding. However, she is asking for your help for some of these calculations.

Help Jen calculate the velocity of block A after it descends a total of 0.5 m from rest. 0.3 m 0.2 m A After some experiments, it turns out the current mechanism is not very user-friendly. For instance, users have to ensure they have enough physical strength to smoothly descend block A (see the figure below). To increase workforce diversity, Jen is seeking for a better control of block A descending velocity. Help her propose one mechanism that is more ergonomic. 0.3m 0.2 m A Jen is a project manager at a construction site with a very low ratio of female to male workers.
