Let the speed of joke is 4 m/s along the x-axis
train speed is 10m/s along negative x-axis
then the relative speed of joke is 10-4 = 6 m/s along the negative x-axis as the ground is stationary.

A science student is riding on a flatcar of a train traveling along a stralght horizontal track at a constant speed of 12.0 m/s. The student throws a ball into the alr along a path that he judges to make an initial angle of 50.0 with the horizontal and to be in line with the track. The student's professor, who is standing on the ground nearby, observes the ball to rise vertically. How high does she see the ball rise?...

A train is traveling at 30.0 m/s relative to the ground in still air. The frequency of the note emitted by the train whistle is 262 Hz. The speed of sound in air should be taken as 344 m/s. Part AWhat frequency fapproach is heard by a passenger on a train moving at a speed of 18.0 m/s relative to the ground in a direction opposite to the first train and approaching it? Express your answer in hertz. Part B What frequency frecede is heard...
A science student is riding on a flatcar of a train traveling along a straight, horizontal track at a constant speed of 9.20 m/s. The student throws a ball into the air alonga path that he judges to make an initial angle of 68.0° with the horizontal and to be in line with the track. The student's professor, who is standing on the ground nearby, observes the ball to rise vertically. How high does she see the ball rise? Need...
A 280-kg flatcar 22 m long is moving with a speed of 6.0 m/s along horizontal frictionless rails. A 95-kg worker starts walking from one end of the car to the other in the direction of motion, with speed 2.5 m/s with respect to the car. In the time it takes for him to reach the other end, how far has the flatcar moved?
[5] A train of mass mtrain runs along a straight track at speed v. What is the angular momentum of the train relative to a point P that is distance D from the track on the right side (with respect the direction of travel of the train) of the track? [10 pts]
A spaceship moves by Earth at 2.4 × 10^8 m/s. A satellite moves by Earth in the opposite direction at 1.6 × 10^8 m/s. Use the Galilean transformation to calculate the speed of the satellite relative to the spaceship and comment on your answer.
A passenger on a moving train walks at a speed of 2.30 m/s due north relative to the train. The train is traveling at 3.5 m/s due east relative to the ground. What are the magnitude and direction of the velocity of the passenger relative to the ground? magnitude m/s direction ° north of east
A railroad flatcar of weight 7840
N can roll without friction along a straight horizontal track.
Initially, a man of weight 557 N is standing on the car, which is
moving to the right with speed 25 m/s; see the figure. What is the
change in velocity of the car if the man runs to the left so that
his speed relative to the car is 5.0 m/s?
A passenger on a moving train walks at a speed of 1.40 m/s due north relative to the train. The passenger's speed with respect to the ground is 4.5 m/s at an angle of 32.0° west of north. What are the magnitude and direction of the velocity of the train relative to the ground?
