A man standing still at a train station watches a train move past him eastward at 20 m/s. Two boys inside the train throw a baseball. The ball is thrown westward, at a speed of 5.0 m/s relative to the boy that throws the ball. What is the velocity of the ball as measured by the man in the train station? Assume that eastward corresponds to positive values of displacement.
A man is running on a straight road that is perpendicular to a train track; he runs away from the track at a speed of 12 m/s. The train moves at 30 m/s with respect to the track. What is the speed of the man with respect to a passenger sitting at rest in the train?
The velocity of a particle in reference frame is m/s. The velocity of reference frame with respect to reference frame is and the velocity of reference frame with respect to is .$ What is the velocity of the particle in reference frame ?
