A ball is thrown vertically upward. At the highest point in its path, which of the following statements is correct?a)The velocity is zero and the acceleration is pointing downb)The velocity and acceleration are both zeroc)The acceleration is zero and the velocity is pointing upd)The acceleration is zero and the velocity is pointing downCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

Option A is correct because at the maximum height the velocity become zero and the acceleration is acceleration due to gravity

Answer

A is correct because, if you imagine this situation, you will find that, at the highest point the ball has no velocity, if present then the ball,should reached more hight but is it,?,no.so the velocity is 0.and there is an acceleration pointing down, the, acceleration here is gravitational acceleration, g, and g act along down point for any partical, in earth, so therw is a acceleration in pointing down,

Answer

At the final point, body stops so v=0 but acceleration always acts downwards hence option A

Answer

(a) is correct.
V is zero at max height but gravity is always act on a body weither the body is on the earth surface or on some height.

Answer

Correct answer is A because, as ball is vertically thrown up velocity at the highest point will be zero and acceleration due to gravity always act downward

Answer

What is mean by velocity

Answer

At the highest point in its path, the ball is momentarily at rest before it starts to fall back down. This means its velocity is zero. Additionally, the acceleration due to gravity is always directed downward, so the acceleration is also pointing downward. Therefore, the correct statement is option A: The velocity is zero and the acceleration is pointing down.

Explanation:
- Velocity at the highest point: At the highest point in its path, the ball momentarily stops moving upward and starts to fall back down. This means its velocity is zero at this point. Velocity is a vector quantity that describes both the speed and direction of motion. Since the ball is not moving at the highest point, its velocity is zero.

- Acceleration at the highest point: The acceleration due to gravity is always directed downwards. It acts to accelerate any object in free fall towards the Earth's surface. At the highest point in the ball's path, the acceleration due to gravity is still present and pointing downward. This is because the ball is still subject to the gravitational force even though it has momentarily stopped moving upward. Therefore, the acceleration is pointing down.

- Relationship between velocity and acceleration: Velocity and acceleration are related but distinct quantities. Velocity describes the rate of change of displacement, while acceleration describes the rate of change of velocity. In this case, the ball's velocity is zero at the highest point, indicating it has momentarily stopped moving. However, the acceleration due to gravity is still present and pointing downward. This means the ball will start to accelerate downward and increase its velocity as it falls back down.

To summarize, at the highest point in its path, the ball has zero velocity and the acceleration due to gravity is pointing downward. These conditions indicate that the correct statement is option A: The velocity is zero and the acceleration is pointing down.
