A person sitting in an open vehicle moving at a constant velocity throws a ball vertically up into air. Where does the ball fall? Explain your answer.
Ignoring air friction the ball will fall on the vehicle.both ball and vehicle are moving at same speed even in air they will be moving together at same speed.
The ball falls back to the hands. Both the person and the ball are moving at the same constant horizontal velocity.
The ball falls back to the person (the thrower) since its horizontal velocity is not affected by the verticle projection provided friction due to air particles is negligible.
The ball falls back to the hand of that person
The ball falls back to the vehicle.
The ball travels at the same velocity ( including direction) as the vehicle due to inertia.
The ball falls back to the person in the vehicle.
The ball moves with same horizontal velocity as the vehicle
The ball will just fall back to the same point of projection since the ball and the vehicle are moving with the same horizontal velocity
Because of inertia. Ball will land on vehicle. Air resistance neglected
I agree with all the explanations above but question does not say we ignore air resistance. so exact answer is opposite in areal exam situation.
The vehicle, the person and the stone are all moving through the air, thus the resultant friction against the motion of the bodies is negligible.
it falls back in the hands
The ball will fall into the open moving car. This is because the constant velocity of the open moving car is equivalent to the velocity with which the projectile moves.
Ball falls bact to the vehicle.
The ball has both horizontal and vertical displacements. The horisonantal displacements of the ball is the same as that of the vehicle.
