am i doing this problem right? help please!
a particle initially located at the origin has an acceleration of a=3 j m/s2 and an initial velocity of vi= 5 i m/s. find a.) the vector position and velocity of the particle at any time t and b.) the coordinates and speed of the particle at t=2 s.
so for a.) i got the equation xf=0+5(t)+.5(3)(t2) I am not really sure where to go from there. it says for any time, so do i just put in any number
to get the velocity i did vf=5+3(t)
for b.) do i just plug in 2 for the times above. I am really not sure if I am doing this right
