1. The problem statement, all variables and given/known data hi,guys! Problem: s(t)=At-Bt^2+Ct^3,where A,B,C is know constants. What is the path,velocity and accelartion after 2s from begining of motion. 2. Relevant equations 3. The attempt at a solution So v(t)=s'(t) a(t)=s''(t) But where i get confuzed is when im asked to calculate v,s,a after 2s. If i would calculate s(t=2s),v(t=2s),a(t=2s) it would be at time 2s not after 2s,am i right? so how to calculate after 2s?
