Valor da aceleração e do tempo de queda
A velocidade v de uma partícula disparada obliquamente move-se no plano xy com sua velocidade dada por v= 10i+(30-10)j, em metros por segundo e t>0 dado em segundos.
Qual é a Aceleração para T=2s?
Quando a aceleração será nula,se possível? e a velocidade?
Determine o tempo de queda e o alcance da partícula
