(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

v_{x}(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

2. Relevant equations

v_{x}(t)=a-bt^2

3. The attempt at a solution

a)X_{f}=x_{1}+ V_{1}t + 1/2at^2

X_{f}=0 + 4(0)+1/2(9.8)(0)^2

c)V_{2}^2= V_{1}^2 + 2aD

-V_{1}^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.
