1 - One stone is thrown from the top of a building (as we can see in the picture below), falling 15 meters after the building, after 5 seconds. We also know that 3 seconds after the throwing, the stone is at the same level of the throwing platform. Treating this stone as a pontual object, calculate:

a) the velocity components at the instance of the throwing;

b) the heigh (h) of the building;

c) the average velocity vector since the throwing till the impact in the ground, and its module. Chose your own reference to use.
