Aball is thrown straight up in the air. which of these statements about its kinetic energy is true? a ball is thrown straight up in the air. which of these statements about its kinetic energy is true?
a : the ball has the least kinetic energy at the end of its flight (before it is caught).
b: the ball has the least kinetic energy at the top of its flight.
c: the ball has the least kinetic energy at the start of its flight.
d: the ball has the most kinetic energy halfway to the top of its flight.

B: The ball has the least kinetic energy at the top of its flight.

Explanation:

As we know that the ball is thrown up into the air

so here the kinetic energy of the ball is initially vertically upwards and it is given by the person who throws up the ball

Now since the ball is moving up in the air so here motion of ball is under the deceleration due to gravity.

So as the ball is moving upwards the speed of the ball will decrease continuously and it will become zero as soon at ball will reach the top of its path

So here correct answer will be

B: The ball has the least kinetic energy at the top of its flight.

does it have any answear choices.
