A locomotive of mass m= 1.134 X 105 kg uses 37.8 kW of power to accelerate at a constant rate for 15.0 s. a) The locomotive has an initial velocity of 0.500 m/s east. Calculate the locomotive’s speed after 15.0 s. After 15.0 s, the locomotive travels east at a constant speed and then collides and couples with a train of four cars. Each of the cars has half the mass of the locomotive. Before the collision, the train was...
