Superman is jogging alongside the railroad tracks on the outskirts of Metropolis at 150 km/h. He overtakes the caboose of a 500-m-long ffreight train traveling at 90 km/h. At that moment he begins to acclerate at +10m/s^2.

A) How long does it take for Superman to pass the train?

B) How far will the train have traveled before superman passes the locomotive?

C) What is superman's final speed?
