A train traveling at 48.46 m/s is heading towards a station 339 m away. If the train must slow down with constant deceleration (a) into the station, how long does it take to come to a complete stop, in seconds? (round to 2 decimals)

Athin, square metal plate measures 14 cm on each side and has emissivity of 0.60. the plate is heated to a temperature of 745°c. what is the rate at which the plate radiates energy ? the stefan-boltzmann constant is 5.67 × 10-8 w/(m2 ? k4). remember that the plate will radiate energy from both its top and bottom surfaces.
