Two particles move on a horizontal line, starting at t = 0, with respective laws of motion S1(t)=t^3-6t & S2(t)=t^2+14t, and where S is measured in meters and t in minutes. a) Determine if these two bodies are at any moment t> 0.
b) If so, calculate the velocity of each of the particles at that instant.

(Must be solved with derivatives)

t = 1/400 h   ⇔ 0.0025 h ⇔ 9s ⇔ 0.15 m

any of the answers are correct.
