Homework Statement
vx(t)=a-bt^2
a=4.0 m/s
b=2.0 m/s^2
At t=0 the object is at x=0
a)Calculate objects position as a function of time
b)Calculate objects acceleration as a function of time
c)What is objects maximium positive displacement from the origin
Homework Equations
vx(t)=a-bt^2
The Attempt at a Solution
a)Xf=x1 + V1t + 1/2at^2
Xf=0 + 4(0)+1/2(9.8)(0)^2
c)V2^2= V1^2 + 2aD
-V1^2/2a)=D
-16/-4=4
I'm particularly stumped on question a & b because I'm not quite sure what ithe question is asking and I'm not entirly confident that C is correct. Any help is appreciated.
