OpenStudy (welshfella):
use one of the equations for motion under constant acceleration;- v = u + at u = 0 , v = 325, a = 15.6 , t = ? solve for t.
OpenStudy (welshfella):
plug in those values and solve for t:- 325 = 0 + 15.6t
OpenStudy (shaleiah):
340.6
OpenStudy (welshfella):
no 15.6t = 325 divide both sides by 15.6
