A ball is thrown straight up in the air. When the ball reaches its highest point, which of the following is true?a. It is in equilibrium. b. It has zero acceleration. c. It has maximum momentum. d. It has maximum kinetic energy. e. None of the above

option E.

Explanation:

When the ball is at the highest point the velocity of the ball is zero.

At the height point the kinetic energy is zero and potential energy is maximum.

At maximum point momentum cannot be maximum because velocity is zero.

Acceleration on the ball is equal to acceleration due to gravity on the ball.

Hence, the correct answer is option E.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.
