The position of a particle moving along the x-axis depends on the time according to the equation x=ct^(2)-bt^(3), where x is in meters and t in seconds. (a)What units must c and b have ?Let their numerical value be 3.0 and 2.0, respectively. (b)What distance does the particle move. (c)WHat is its displacement? At t=1.0,2.0,3.0 and 4.0 ,What are (d) its velocities and (e) its accelretions? |
