Initially when the ball is thrown up it has some velocity. And due to this velocity the ball has some initial kinetic energy. Initially the ball is at the ground therefore it has 0 potential energy.
Now when the ball reaches its maximum height the speed of the ball becomes 0 and hence kinetic energy becomes 0 but since now the ball is at it's maximum height therefore now it has potential energy.
Therefore the whole kinetic energy got converted into potential energy.
Therefore answer is kinetic to potential

A ball is thrown upwards with a speed of 19 m/s. it reaches a hight of 18.4 m above the point of release before it falls back down. Specify down as the positive direction and the initial position as the origin. If the balls position after three seconds is -12.9 meters, what is the distance traveled by the rock? The acceleration due to gravity is 9.8 m/s^2 down. The answer is 23.9 meters, how would i solve this?

A blue ball is thrown upward with an initial speed of 22.8 m/s, from a height of 0.6 meters above the ground. 2.8 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 7.7 m/s from a height of 28.2 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s2. ) What is the speed of the...

Explore A baseball is thrown from the top of a tall building with an initial velocity of 10 m/s from a height of h= 11.5 m above the ground. Find its speed when it reaches the ground (a) if its launch angle is 37°, and (b) if it is launched horizontally. Conceptualize As the baseball moves upward and to the right, the force of gravity accelerates it downward. The vertical component of its velocity decreases in magnitude until the baseball...

A ball is thrown vertically upwards at a speed of 15m/s at the edge of a 20m deep well. The ball is released at a height of 2m above ground level. How high does the ball rise above ground level? If the ball on its downward path falls down the well, how many seconds elapse between releasing the ball and it striking the bottom of the well? Assume that the downward acceleration is 9.81 m/s2 .
