Question

A student drops a basketball into a pool from a height of 5 meters while a friend records the approximate splash height. They want to make bigger splash in their next trial. How can they achieve this?

1. They can use a ball with the same diameter but more mass
2. They can drop the same ball with less speed
3. They can use a ball with the same diameter but less mass
4. They can drop the same ball from a lower height

Answer 2

[AI-generated answer — Step-by-Step Bot]

To achieve a bigger splash in their next trial, the student can try the following steps:

1. Decrease the diameter of the ball: Using a ball with a smaller diameter can help concentrate the impact force on a smaller surface area, leading to a bigger splash.
2. Increase the mass of the ball: Using a ball with a greater mass can increase the force of impact when it hits the water, resulting in a larger splash.
3. Increase the speed of the ball: Dropping the ball with a higher initial velocity can generate a larger splash upon hitting the water.
4. Drop the ball from a higher height: Increasing the height from which the ball is dropped provides it with more gravitational potential energy. When the ball hits the water from a greater height, it can create a larger splash.

Therefore, to make a bigger splash, the best options would be:
1. Use a ball with the same diameter but more mass.
2. Drop the same ball from a higher height.

Answer 3

[AI-generated answer — Explain Bot]

To achieve a bigger splash in the next trial, the student and their friend can consider the following options:

1. They can use a ball with the same diameter but more mass: Increasing the mass of the ball will increase the force with which it hits the water, resulting in a bigger splash. This can be achieved by using a ball made of a denser material or by adding weight to the ball.

2. They can drop the same ball with less speed: The speed at which the ball hits the water affects the size of the splash. If the ball is dropped from a lower height or if its initial velocity is reduced, it will result in a smaller impact force and a smaller splash. On the other hand, dropping the ball with a higher initial velocity would result in a larger splash.

3. They can use a ball with the same diameter but less mass: Decreasing the mass of the ball will reduce the force with which it hits the water, resulting in a smaller splash. This can be achieved by using a ball made of a less dense material or by removing weight from the ball.

4. They can drop the same ball from a lower height: The height from which the ball is dropped has a significant impact on the size of the splash. Dropping the ball from a lower height will result in a smaller impact force and a smaller splash. However, it is important to note that dropping the ball from a very low height may not generate enough force to create a noticeable splash.

Each of these options will affect the size of the splash differently. The students can experiment with these variables to determine the best method to achieve a bigger splash in their next trial.
