The velocity time graph for the veticaly component of the velocity of a body thrown upwards from the ground and landing on the roof of a building is given in the figure.The height of the building is:

A stone is dropped from the roof of a building takes 4s to reach ground. The height of the building is

Velocity-time graph of a body thrown vertically up is

A stone is thrown downwards with velocity 10 m/s from the roof of a builng and it reaches the ground with speed 40 m/s. the height of the building would be

A stone is thrown downwards with velocity 10 m/s from the roof of a builng and it reaches the ground with speed 40 m/s. the height of the building would be

A body of mass 1 kg falls to the ground from the roof of a building 20 m high. Find its (ii) velocity when it reaches the ground,

The angle of elevation of the top of a building and the top of the chimney on the roof of the building from a point on the ground are x and 45^(@) respectively .The height of building is h metre .Then the height of the chimney (in metre ) is :
