Na questão, quando necessário, utilize:
⋅ aceleração da gravidade: g = 10 m/s2;
⋅ cos 30° = sen 60° = √3/2;
⋅ cos 60° = sen 30° = 1/2;
⋅ fator de Lorentz = 
Em seguida, o plano é inclinado para 30°, conforme figura 2; sendo que, nesse momento o bloco fica na iminência de descer ao longo do plano.
Posteriormente, uma mola ideal é presa ao topo do plano inclinado; deforma-se de 5 cm essa mola e prende-se a outra extremidade dela ao bloco, conforme figura 3.
Observa-se, então, que o bloco permanece em repouso, porém, agora na iminência de subir ao longo do plano inclinado.
Nessas condições, a constante elástica da mola, em N/m, vale
Na questão, quando necessário, utilize:
⋅ aceleração da gravidade: g = 10 m/s2;
⋅ cos 30° = sen 60° = √3/2;
⋅ cos 60° = sen 30° = 1/2;
⋅ fator de Lorentz =
quando somados resultam em um vetor cujo módulo vale
1,0 u. Ao se calcular a diferença entre obtém-se um
vetor cujo módulo vale 5,0 u. Considere um vetor
com módulo igual ao do vetor 
e
formando um ângulo de 120° em relação ao vetor 
Nessas condições, a soma dos vetores resultará em um vetor de módulo igual a
Na questão, quando necessário, utilize:
⋅ aceleração da gravidade: g = 10 m/s2;
⋅ cos 30° = sen 60° = √3/2;
⋅ cos 60° = sen 30° = 1/2;
⋅ fator de Lorentz =
Em determinado instante A e B sofrem uma colisão perfeitamente elástica. Após essa colisão, B atinge uma altura vertical máxima, medida em metros e em relação à horizontal de referência, igual a
Na questão, quando necessário, utilize:
⋅ aceleração da gravidade: g = 10 m/s2;
⋅ cos 30° = sen 60° = √3/2;
⋅ cos 60° = sen 30° = 1/2;
⋅ fator de Lorentz =
Observa-se que a partícula A se encontra em movimento uniforme desde t = 0 e que a partícula B só inicia seu movimento uniformemente variado a partir do repouso, em t = 2,0 s.
Nessas condições, a distância, em metros, que separa as duas partículas, A e B, no instante t = 8,0 s, vale
