Calculate the change in the kinetic energy (KE) of the bottle when the mass is increased. Use the formula KE = one half. mv2, where m is the mass and v is the speed (velocity). Assume that the speed of the soda bottle falling from a height of
0.8 m will be 4 m/s, and use this speed for each calculation.

Record your calculations in Table A of your Student Guide.

When the mass of the bottle is 0.125 kg, the KE is kg m2/s2.
0.25 or 0.5 or 1 or 2
When the mass of the bottle is 0.250 kg, the KE is kg m2/s2.
0.5 or 1 or 2 or 4
When the mass of the bottle is 0.375 kg, the KE is kg m2/s2.
3 or 3.75 or 6 or 9
When the mass of the bottle is 0.500 kg, the KE is kg m2/s2.
2 or 4 or 5 or 8
