A railroad car is moving in the +x direction on a straight and level track A person in the railroad car throws a ball the ball follows trajectory shown relative to the railroad car from an inspection of the trajectory what can be concluded about the motion of railroad car ? Treaty axis along vertical

A car is traveling at a velocity of 10 km/h on a straight road. The driver of the car throws a ball. If the ball is to reach back to the driver, the direction of throw makes the following angle with the direction of the car:

A block of mass m sits at rest on a frictionless table in a rail car that is moving with speed v_(c) along a straight horizontal track (fig.) A person riding in the car pushes on the block with a net horizontal force F for a time t in the direction of the car's motion. What is the final speed of the block according to a person in the car ?

Two persons A and B travelling at 60 km//hr^(–1) in their cars moving in opposite directions on a straight road observe an airplane. To the person A, the airplane appears to be moving perpendicular to the road while to the observe B the plane appears to cross the road making an angle of 45° . (a) At what angle does the plane actually cross the road (relative to the ground). (b) Find the speed of the plane relative to the ground.

A person riding in the car pushes on the block with a net horizontal force F for a time t in the direction of the car's motion. In terms of F,m & t , how far did the the force displace the object according to the person in car ?

A boy is standing on a flatcar that is moving with uniform acceleration on a level track. At the instant when flatcar is moving with velocity 10 m/s due east the boy throws a ball with velocity 20 m/s in direction 45° above the east with respect to the flatcar in plane of motion of flatcar. What should be the acceleration of the flatcar so that the boy can catch the ball without moving anywhere on the flatcar? Assume acceleration due to gravity 10 m/ s^(2) .
