Homework Statement
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 beginning of motion.
Homework Equations
The Attempt at a Solution
So
v(t)=s'(t)
a(t)=s''(t)
But where i get confuzed is when I am 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?
