ENEM 2019 - Em qualquer obra de construção civil é fundamental a utilização de equipamentos de prote

(ENEM 2019) In any civil construction work, the use of personal protective equipment, such as helmets, is fundamental. For example, the free fall of a 2.5 kg brick from a height of 5 m, whose impact against a helmet can last up to 0.5 s, results in an average impulsive force greater than the weight of the brick. Assume that the gravitational acceleration is 10 m/s² and that the effect of air resistance is negligible. The average impulsive force generated by this impact is equivalent to the weight of how many identical bricks? A) 2 B) 5 C) 10 D) 20 E) 50 ================== Did you like the video?
