Question

factors that affect kinetic energy quick check
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 a bigger splash in their next trial. how can they achieve this? (1 point)
they can use a ball with the same diameter but less mass.
they can drop the same ball with less speed.
they can use a ball with the same diameter but more mass.
they can drop the same ball from a lower height.

Explanation:

Kinetic energy formula is \(KE=\frac{1}{2}mv^{2}\). A bigger splash means more kinetic energy. Mass (\(m\)) and speed (\(v\)) affect kinetic energy. Using a ball with more mass (same diameter) increases \(m\). Dropping from a lower height or with less speed reduces \(v\). A ball with less mass reduces \(m\).

Answer:

They can use a ball with the same diameter but more mass.
