m was meters, what confused me was that there was no variable given for time, by standard we use "t" in class and this position vector had no variable for time so I couldn't differentiate :/ Do you think maybe my teacher made an error typing the worksheet? I don't think there is enought...
Unit Vector notation??
The vector position of a particle varies in time according to the expression r = (3.0i +6.0j)m
Find expressions for velocity and acceleration as functions of time.
I have NO IDEA HOW TO DO THIS.
Homework Statement
A two stage rocket is launched with an average acceleration of +4 m/s/s. After 10 seconds, a second stage is activated and the rocket's acceration is now +6 m/s/s.
Part A: Find the vertical displacement of stage one of the rocket, before accleration changes to 6...
