Arailroad 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 200 kg and is traveling east with a velocity of magnitude 5.40 m/s . find the final velocity of the car in each case, assuming that the handcar does not leave the tracks.

The final velocity of the car is 6.06 m/s in east.

Explanation:

Given that,

Total mass = 200 kg

Velocity = 5.40 m/s

Suppose we find the relative to the initial motion of the car

An object with the mass of 22.0 kg is thrown backward out of the car with a speed of 5.40 m/s relative to the initial motion of the car

We need to calculate the final velocity of the car

Using formula of relative motion

Put the value into the formula

Hence, The final velocity of the car is 6.06 m/s in east.

i think the answer is a, hope this is right, that would be my best guess.
