Considere a função horária dos espaços =75−15.t+52.2.t para um móvel qualquer, com todas as unidades no sistema internacional de unidades (S. I). E responda respectivamente quais são os valores da posição inicial, velocidade inicial, aceleração e o(s) instantes onde esse móvel passa pela origem a) -75m, 15m/s, 10m/s² e o móvel não passa pela origem.

b) 75m, 15m/s, -5m/s² e t = 3s.

c) 75m, -15m/s, 5m/s² e o móvel não passa pela origem.

d) -75m, -15m/s, 5m/s² e t = 3s.

e) -75m, 15m/s, -5m/s² e t = 3s.

Explanation:

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
