1. The problem statement, all variables and given/known data 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 2. Relevant equations vx(t)=a-bt^2 3. 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.
