Question

rita climbs a ladder to the top of a water slide, waits her turn, and then slides down the slide into a pool. which series describes the energy changes of her actions?
o kinetic - mechanical - potential
o kinetic - potential - kinetic
o potential - kinetic - potential
o potential - mechanical - kinetic
possible points: 1.7

Explanation:

1. When Rita climbs the ladder, she uses her body's kinetic energy (from moving) to gain height. At the top (waiting), she has potential energy (due to height). When sliding down, potential energy converts to kinetic energy (motion). So the sequence is kinetic (climbing) → potential (waiting) → kinetic (sliding).
2. Analyze each option:

• First option: Incorrect energy types (mechanical not part of the main conversion here).
• Second option: Correct sequence as explained.
• Third option: Wrong order (starts with potential but climbing uses kinetic).
• Fourth option: Incorrect energy types (mechanical not relevant to this simple conversion).

Answer:

B. kinetic – potential – kinetic (assuming the second option is labeled B, as per the order: kinetic (climbing) → potential (waiting) → kinetic (sliding))
