A particle moves according to a law of motion s = f(t) = t3 - 12t2 + 21t, t 0, where t is measured in seconds and s in feet. v(t) = 3t^2 - 24t 21 a(t) = 6t - 24 e) Find the total distance traveled during the first 8 s. i) When is the particle speeding up?...

i dont know if this is correct though; 4x(5) = 37 4x=37-5 4x/4=32/4 x=8 check: x=8 4(8)=37-5 32=32
