What is Xman(t), the position of the man as a function of
Answer symbolically in terms of the variables d, Vman, and
Speed of the man = vman.
Hence, distance moved by the man in time t = Speed x Time =
At t = 0 s, the position of the man was d unit behind the door
of the stopped bus, i.e., xman ( t = 0 ) = - d.
Therefore, xman ( t ) = - d +
