A ball is thrown with a speed of 12 m / s directed vertically upwards from a window located 16 m above the ground. If it is assumed that friction with the air does not affect the movement of the ball and that its acceleration is that of gravity g = 9.8 m / s2 downwards. Determine: a) the velocity V and the height y of the ball above the ground as a function of time t b) the highest position the ball reaches on the ground and the corresponding value of time t c) the time in which the ball hits the ground and the corresponding velocity. d) draw the curves (v - t) and (y - t)

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
