A person sitting in a moving train throws a ball vertically upwards. How does the ball appear to move to an observer outside the train?

A person standing downward on a tower throws a stone vertically upward with a velocity u and drops another stone downward with same initial velocity. Which stone will strike the earth with a larger velocity ?

A Person standing on a tower throws a stone vertically upward with a velocity u and drops another stone downward with the same initial velocity. Which stone will strike earth with larger velocity ?

A person standing on the edge of a well throws a stone vertically upwards with an initial velocity 5ms^(-1) . The stone gone up, comes down and falls in the well making a sound. If the person hears the sound 3 seconds after throwing the the depth of water (neglect time travel for the sound and take g=10ms^(-2) )

A cart is moving along +x direction with a velocityof 4 m//s . A person on the cart throws a stone with a velocity of 6 m//s relative to himself. In the frame of reference of the cart the stone is thrown in y-z plane making an angle of 30^@ with vertical z-axis. At the highest point of its trajectory, the stone hits an object of equal mass hung vertically from the branch of a tree by means of a string of length L. A completely inelastic collision occurs, in which the stone gets embedded in the object. Determine : (i) The speed of the combined mass immediately after the collision with respect to an observer on the ground,

A person standing on the edge of well throws a stone vericall upwards with an initial velocity 5 ms^-1 . The stone goes up, comes down and falls in the well making a sound. If the person hears the sound 3 s after throwing , the water is at a depth from ground given by (neglect time of travel for the sound and take g= 10 ms^-2 )

A man standing on the edge of the terrace of a high rise building throws a stone, vertically up with at speed of 20 m//s . Two seconds later, an identical stone is thrown vertically downwards with the same speed of 20 m ,. Then
