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 kgkg and is traveling east with a velocity of magnitude 5.10 m/sm/s. Find the final velocity of the car in each case, assuming that the handcar does not leave the tracks. a) An object with a mass of 30.0 kgkg is thrown sideways out of the car with a speed of 2.50 m/sm/s relative to the car's initial velocity. Express your answer with the appropriate units. b) An object with a mass of 30.0 kgkg is thrown backward out of the car with a velocity of 5.10 m/sm/s relative to the initial motion of the car. Express your answer with the appropriate units. c) An object with a mass of 30.0 kgkg is thrown into the car with a velocity of 6.00 m/sm/s relative to the ground and opposite in direction to the initial velocity of the car. Express your answer with the appropriate units.
