Considerando que você comece a caminhar em velocidade constante, inicialmente a 350 m de um ponto referencial escolhido. Você caminha a 1 m/s no sentido de encontro desse referencial. Podemos dizer que a Equação Horária desse MRU e o tipo de movimento são, respecitvamente:
Escolha uma:
a. S(t)=350−1t, movimento retrógrado
b. S(t)=350−1t, movimento progressivo.
c. S(t)=350+1t, movimento progressivo
d. S(t)=−350+t, movimento progressivo.
e. S(t)=350+1t, movimento retrógrado.

Two red blood cells each have a mass of 9.0 multiply. gif 10-14 kg and carry a negative charge spread uniformly over their surfaces. the repulsion arising from the excess charge prevents the cells from clumping together. one cell carries −2.50 pc of charge and the other −3.10 pc, and each cell can be modeled as a sphere 7.5 μm in diameter. (a) what speed would they need when very far away from each other to get close enough to just touch? assume that there is no viscous drag from any of the surrounding liquid. answer is: 321 m/s how do i find this (b) what is the maximum acceleration of the cells in part (a)? answer is: 1.38e+10 m/s2 how did they find this answer
