Arailroad handcar ismoving along straight, frictionless tracks with negligible airresistance. in the following cases, the car initially has a totalmass (car and contents) of 170 image for a railroad handcar ismoving along straight, frictionless tracks with negligible airresistance. in and is traveling east with a velocity ofmagnitude 4.60 m/s. find the final velocity of thecar in each case, assuming that the handcar does not leave thetracks.
a.)
an object with a mass of 22.0 image for a railroad handcar ismoving along straight, frictionless tracks with negligible airresistance. in is thrown sideways out of the car with a speedof 2.50 m/s relative to the car's initialvelocity.
b.)
an object with a mass of 22.0 image for a railroad handcar ismoving along straight, frictionless tracks with negligible airresistance. in is thrown backward out of the car with avelocity of 4.60 m/s relative to the initial motion of thecar.
c.)
an object with a mass of 22.0 image for a railroad handcar ismoving along straight, frictionless tracks with negligible airresistance. in is thrown into the car with a velocity of6.00 m/s relative to the ground and opposite indirection to the initial velocity of the car.
