The graph of an object moving with speed v for a time t is shown below.

The graph that shows the distance s travelled by the same object for a time t is

Two balls are thrown horizontally, one from the window of first floor which is $$3 \mathrm{~m}$$ high from the ground and second from the second floor which is $$6 \mathrm{~m}$$ high from the ground, of a multi storey building, with the same speed of $$6 \mathrm{~ms}^{-1}$$. Calculate the distance that will separate the two balls when they hit the ground.

When two objects are moving along a straight line in the same direction, the distance between them increases by $$6 \mathrm{~m}$$ in one second. If the objects move with their constant speed towards each other the distance decreases by $$8 \mathrm{~m}$$ in one second, then the speed of the objects are :

A body is projected vertically upwards. The times corresponding to height $$h$$ while ascending and while descending are $$t_1$$ and $$t_2$$, respectively. Then, the velocity of projection will be (take, $$g$$ as acceleration due to gravity)
