Are you having trouble finding the differential of the equation for displacement?
I have an exam coming up and I just want to practice some before tomorrow because I'm not sure how to do them at all!
Were you aware that the equation for velocity is found by differentiating the equation for displacement? Put up your work so far and see what you get
v(t)=2*4*t^3-5*3*t^2+1 a(t)=2*4*3^2-5*3*2*t
