Thank you, I really appreciate that help. We haven't done derivatives yet and its hard to see without that knowledge...

Physics
A 0.150 kg particle moves along an x axis according to x(t) = -13.00 + 2.00t + 3.50t2 - 2.50t3, with x in meters and t in seconds. In unit-vector notation, what is the net force acting on the particle at t = 3.45 s? I tried solving using s=Vit + (.5)at^2 but I can't find t...

Math
First Estimate, and then multiply to get the exact answer. 2*4/7*7*5/11*5
