Question

select all the correct answers. which situations describe an elastic collision? two glass marbles bounce off each other. rodrick flops onto his sofa and sinks into the cushion. a tossed water balloon flattens when it lands on the grass. a bowling ball knocks over five pins.

Explanation:

An elastic collision conserves both momentum and kinetic energy, with minimal deformation. Glass marbles bouncing off each other experience little deformation, conserving kinetic energy, making this elastic. The other options involve deformation (sofa cushion, water balloon flattening) or energy loss (bowling pins), classifying them as inelastic.

Answer:

A. Two glass marbles bounce off each other
