Atenção! Esta questão foi postada ha mais de 30 dias!
Exercício de movimento unformemente acelerado
Exercício:
Um balão sobe verticalmente com movimento uniforme . Seis segundos após a partida , o piloto abandona uma pedra que alcança o solo nove segundos após a saída do balão . Determine , em metros , a altura em que a pedra foi abandonada.Despreze o efeito do ar e adote g= 10m/s²
Informações Adicionais:
A RESPOSTA É 30 METROS
Se o balao sobe com uma velocidade V1 entao temos que a pedra foi abando nada de uma altura S=6.V1. Tomando como S uma posicao de nosso referencial sabemos que a pedra foi “lancada para cima” de S com velocidade V1. Pela equacao do espaco temos 0=6.V1+V1.t-5t2 para 9 segundos apos a saida do balao, mas por equacao delimitamos o tempo entre 6 e 9 segundos, o que nos da 3 segundos. Substituindo t por 3 temos:
0=6.V1+3.V1-45 >>> 9V1=45 >>>> V1=5m/s >>> Se o local de lancamento da pedras foi S=6.V1, temos S=30m
S=S0+V0.t±(at2)/2 << Equacao do espaco
Resposta: A pedra foi abandonada de uma altura de 30metros
muito obrigada renato!
I don’t know if it’s just me or if everybody
else encountering problems with your site. It
appears as if some of the text within your posts are running off the screen. Can somebody else please comment and let me know if this
is happening to them too? This could be a problem with my
browser because I’ve had this happen before. Kudos
