Explanation:
The particle will be at rest when its velocity is equal to zero. Recall that the velocity is simply the derivative of the position
with respect to time:
Since
then
Solving for t, we find that the particle will be at rest at
Answer:
10 h
Explanation:
velocidade é a taxa de variação da distância no tempo. é a razão entre a distância e o tempo
de Santos e Curitiba:
distância (d) de 480 km, velocidade (s) de 80 km/h
de Curitiba e Florianópolis:
distância (d) de 300 km, velocidade (s) de 75 km/h
