Kinematics (Calculus Form)
A particle travels along a straight line which passes through and . During the motion the velocity of the particle is metres per second, where seconds is the time measured from a certain instant. The particle passes through when and through when . Find, in terms of , the acceleration of the particle and its distance from at any instant during the motion. Calculate, also, the distance of from .
I don't know how to do this part (don't even understand what it is saying (Worried)): 'Find...its distance from at any instant during the motion'*. Can someone help? Thanks in advance.
*The answer is .
