Particle Position and Time The position of a particle moving along the x axis depends on the time according to the equation x = ct2 - bt3, where x is in meters and t in seconds.
(a) What dimension and units must c have?
s2/ms/m2 m/s2m2/s
What dimension and units must b have?
m3/ss/m3 s3/mm/s3
For the following, let the numerical values of c and
b be 3.3 and 1.0 respectively.
(b) At what time does the particle reach its maximum positive
x position?
s
