Artificial Intelligence (AI) is rarely out of the news - especially during these challenging times, when AI has been suggested as a tool to help end the COVID-19 pandemic. However, many people do not have a full understanding of what AI actually means, how it works, or how it might help.

Em “assume a direção, que vou descansar um pouquinho”, o conectivo sublinhado tem valor:
por t segundos. Ao final desse intervalo de tempo, o módulo da
velocidade do carro atinge o valor v1
. O motorista então,
sem pisar no freio, reduz instantaneamente a aceleração
do veículo pela metade, mantendo-a nesse valor por mais t segundos, ao final dos quais o módulo da sua velocidade
atinge o valor v2
. As respectivas distâncias percorridas
pelo veículo durante cada um dos intervalos de tempo são
denotadas por d1e d2
.
