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
β 1
kg m2/s2.
When the mass of the bottle is 0.250 kg, the KE is
β 2
kg m2/s2.
When the mass of the bottle is 0.375 kg, the KE is
β 3
kg m2/s2.
When the mass of the bottle is 0.500 kg, the KE is
β 4
kg m2/s2.
