A railroad handcar is moving along straight, frictionless tracks with negligible air resistance. In the following cases, the car initially has a total mass (car and contents) of 180 kg and is traveling east with a velocity of magnitude 5.10 m/s. Find the final velocity of the car in each case, assuming that the handcar does not leave the tracks. ▾ Part A An object with a mass of 26.0 kg is thrown sideways out of the car with a speed of 2.10 m/s relative to the car's initial velocity.
