Q1865629
Física
Conforme a figura abaixo, um canhão, inicialmente parado
sobre uma superfície sem atrito, aponta numa direção que
forma um ângulo de 60º com a horizontal e atira uma bala
de 60 kg, cuja velocidade na boca do canhão é de 400
m/s. A massa do canhão é de 1000 kg. Após o tiro, o
canhão desliza sobre a superfície sem atrito e depois entra
em uma região com coeficiente de atrito cinético μc=0,60.
De acordo com os dados, calcule a distância, em metros,
percorrida pelo canhão, na região com atrito, até chegar
ao repouso.

Q1865624
Física
Um sistema massa-mola encontra-se no alto de uma
rampa. Na situação ilustrada na figura abaixo, um
pequeno bloco de massa 1 kg está em repouso e
comprime a mola, de constante elástica 20 N/m, gerando
um deslocamento de 1 m com relação à posição de
equilíbrio da mola. Quando o sistema é liberado, o bloco
desce a rampa e atinge uma superfície horizontal (sem
perder energia ao passar da rampa para a superfície
horizontal). Na superfície horizontal o bloco passa por uma
região com coeficiente de atrito cinético u=0,2 (não há
atrito nas outras regiões) para, em seguida, atingir o ponto
A indicado na figura. Considerando as dimensões
indicadas na figura e que a rampa tem uma inclinação de
30º com relação à superfície horizontal, determine o
módulo da velocidade do bloco, em m/s, quando ele atinge
o ponto A, e assinale a opção correta.
Dado: g = 10 m/s2

Read the text below and answer question.
Time to envision legal recourse for climate refugees
As gradually worsening climate patterns and
severe weather events prompt an increase in human
mobility, people who choose to move will do so with little
legal protection. The current system of international law is
not equipped to protect climate migrants, as there are no
legally binding agreements obliging countries to support
climate migrants.
While climate migrants who flee unbearable
conditions resemble refugees, the legal protections
afforded to refugees do not extend to them. In the
aftermath of World War Il, the United Nations established a
system to protect civilians who had been forced from their
home countries by political violence. Today, there are
almost 20.4 million officially designated refugees under the
protection of the United Nations High Commission for
Refugees (UNHCR), but there is an additional group of
21.5 million people who flee their homes as a result of
sudden onset weather hazards every year.
The UNHCR has refused to grant these people
refugee status, instead designating them as
“environmental migrants,” in large part because it lacks the
resources to address their needs. But with no organized
effort to supervise the migrant population, these desperate
individuals go where they can, not necessarily where they
should. As their numbers grow, it will become increasingly
difficult for the international community to ignore this
challenge. As severe climate change displaces more
people, the international community may be forced to
either redefine “refugees” to include climate migrants or
create a new legal category and accompanying institutional
framework to protect climate migrants. However, opening
that debate in the current context would be very difficult.
Currently, the atmosphere in Europe and the U.S. would
most likely lead to limiting refugee protections rather than
expanding them.
