You are riding in an enclosed train car moving at 90 km/h. Where will the baseball land if you throw it straight upward?

(a) In front of you

(b) Behind you

(c) On your hand

(d) Can’t be decided from the given information

The uniform velocity may be defined as an object's velocity when the object is traveling at equal velocities in equal time intervals.

In the case of uniform velocity, the object's velocity increases or decreases at the same rate.

In an inertial frame of reference, the position of an object is stationary. The car is moving at a uniform speed, and the acceleration of the car is zero. The position of the ball depends on the velocity of the train.

If the horizontal component of the velocity remains constant, the ball will cover the same horizontal distance as the person. The car can be considered an inertial frame of reference.

Therefore, it has the chance to come back directly on your hand. A person covers the horizontal distance at the same time as the ball travels up and down.

Thus, option (c) is the correct answer.
