Another math thing

Given that a car starts from 0 and its distance from position A, traveling in one dimension, is modeled by t^3 - 5t^2 + 1/t^2, give:
1. The car's immediate acceleration at t = 10
2. A model for a car's position given that its acceleration is modeled by t - 1/t and its initial velocity and position are 0

Haven't done these yet as of post creation time, and they're just from my head.

You don't need a calculator for these. Assume x >= 0

We're sitting around getting distracted again

Another math thing

distance = t^3 - 5t^2 + 1/t^2
velocity = 3t^2 - 10t - 2/t^3
acceleration = 6t - 10 + 6/t^4

= 6*10 - 10 + 6/10000 = 50.0006
