PLANO INCLINADO - APLICAÇÕES DAS LEIS DE NEWTON - EXERCÍCIOS - AULA 8 - Prof Boaro ILIMIT EDUCATION

Get to know the platform: www.professorboaro.com.br This is the video of the 8th DYNAMICS CLASS by Prof. Marcelo Boaro. Video of EXERCISE resolution!!!! In DYNAMICS we study the movement of bodies by carefully analyzing the causes of this movement. In this video we will study the INCLINED PLANE. Good studies and may God be with you.

In a second moment, an adult, with three times the weight of the child, slides down this same slide, with also constant acceleration. Treat the bodies of the adult and the child as point masses and 51. (IFCE) Two blocks, A and B, whose masses are mA and mB (mA mB), joined by a bar with mass m much smaller than the mass of A, slide with negligible friction on an inclined plane in the laboratory, as shown in the figure to the side. Since air resistance is negligible under the conditions of this experiment, the correct statement about the tension in the bar is: 52. (UFPR) An employee of a transport company needs to unload a 200 kg counter from his truck. To make the employee's task easier, this type of truck is equipped with a ramp, through which objects can be slid from inside the truck to the ground without much effort. Consider that the counter is completely on the ramp and sliding down. 53. (UERJ) A young man uses parts from a construction toy to build a structure in which he can balance two bodies, connected by an ideal string that passes through a pulley. Observe the diagram 54. (UFU) A block with mass M = 8 kg is supported on an inclined plane and connected to a block with mass m by means of pulleys, as shown in the figure below. The system is in static equilibrium, with the inclined plane fixed to the ground. The pulleys are ideal and the strings have negligible mass. Considering g = 10 m/s2, and that there is no friction between the inclined plane and the block with mass M, mark the alternative that presents the correct value of the mass m, in kg.
