No gráfico é ilustrada a velocidade de uma partícula que se move sobre o eixo x em função do tempo t. conhecido que no instante 2,00s a partícula encontra-se na posição x = 5,00 m, calcule: a) a posição da partícula nos instantes inicial, 5,00 s e 8,00 s. considerando o intervalo
de 2,00 s a 8,00 s, determine
b) considerando o intervalo de 2,00 s a 8,00 s, determine a velocidade média e a aceleração média da partícula
o resultado é a)3,00m, −3,00m e 1,00m b)−667mm/s e 1,00m/s2 porém não consigo desenvolver o exército seria de grande ajuda se alguém pudesse fazer a resolução do exercício
