A student drops the four objects listed from a height of 2 meters into a bucket of water. Which object will have the greatest kinetic energy?
table tennis ball 2.7 grams
baseball 147.0 grams
small rock 248.2 grams
penny 2.5 grams
1 answer
The object with the greatest kinetic energy will be the small rock weighing 248.2 grams. Kinetic energy is directly proportional to the mass of an object, so the rock will have the greatest kinetic energy out of the four objects when dropped from a height of 2 meters.
