Hi everyone,(adsbygoogle = window.adsbygoogle || []).push({});

Could someone please help me on this problem?

1. The problem statement, all variables and given/known data

A particle initially located at the origin has an acceleration of a=1.00jm/s^2 and an initial velocity of V=8.00im/s

a. Find the position vector at any time t (where t is measured in seconds)

b. Find the velocity vector at any time t

2. Relevant equations

r=xi+yj

v=vxi+vyj

3. The attempt at a solution

I know that the velocity is the first derivative of the position vector and the acceleration is the second derivative. However, I am not given the original equation or the velocity vector. Would I use these two equations?

Would it be something like this?

a. r=xi+yj

r=8.00i+1.00j

Could someone please show me what to do or give me a hint?

Thank you in advance
