When a golf ball is dropped into a tray of wet sand, it sinks into the sand and leavesan indentation. the table shows the depth of indentation in the sand when the samegolf ball was dropped from various heights.
golf ball experiment results
height of dropped ball depth of indentation in sand
0.5 meter. 0.2 centimeter 1.0 meter
0.5 centimeter 1.5 meters. 0.9 centimeter. 2.0 meters. 1.6 centimeters
which of these is the best explanation for the recorded results?
a. the kinetic energy of the ball increased as the speed of its fall increased.
b. the ball began to accelerate after it had fallen about 1 meter from where itwas dropped.
c. the amount of moisture in the sand decreased due to evaporation duringthe experiment.
d. the ball moved a random amount of sand each time it hit, causing thedepth of the indentation to vary.
