The position of a particle along the x axis depends on the time according to the equation
x = At2 − Bt3
, where x is in meters and t is in seconds. (a) What SI units must A and B
have? For the following, let their numerical values in SI units be 3.0 and 1.0, respectively. (b)
What time does the particle reach its maximum positive x position? (c)what total path length
does the particle cover in the first 4 seconds?
