Question

A ball thrown into the air has its greatest kinetic energy as it reaches the highest point in its path. please select the best answer from the choices provided t f

Answer 1

Answer:

FALSE

Explanation:

As the ball is thrown in air

then the velocity of the ball has two components

$v_x = v cos\theta$

$v_y = v sin\theta$

now we also know that the acceleration due to gravity is vertically downwards  which is opposite in the direction of vertical velocity

So the acceleration due to gravity will decrease the vertical speed and the horizontal speed will remain constant

So here we can say that the vertical speed sill become minimum as soon as the ball will reach the highest point of its path

So the kinetic energy of the ball is minimum when ball will reach the highest point of its path

So the given statement is FALSE

Answer 2

F - False.

Its greatest kinetic energy is at the point of release.

It has the least kinetic energy, zero, at its highest point in its path.
