5. A stone is thrown up from the top of the architectural building of the Polytechnic University, at an angle of 30.0 ° with the horizontal, and with an initial speed of 20.0 m / s, as shown in the figure. The height of the building is 45.0 meters.

a) How long does the stone take to reach the ground?

B) What is the rapidity of the stone just before hitting the ground?

c) Is it correct that the component v and of the final velocity be negative?

D) Is it correct that the final speed is greater than the initial speed of 20.0 m / s? (e) What would happen if a horizontal wind blows in the same direction in which the stone is thrown and causes it to have a horizontal acceleration component Ax= 0.500m/s ^ 2. Which part of this example, a) or b), will have a different answer?

A 700 gram ball is thrown from the top of a 25 meter tall building. The ball is thrown with an initial speed of 10 m/s at an angle 30 degrees above the horizontal. For our conservation of energy calculations, we will choose the Ball + Earth as our system and use the ground as h = 0. The kinetic energy of the ball when it is thrown = J. When the ball reaches its highest point the kinetic energy is...
