In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. you will use the same mass, 0.250 kg, for each trial, so record this mass in table b for each velocity. then, calculate the expected kinetic energy (ke) at each velocity. use the formula ke = one half. mv2, where m is the mass and v is the speed. record your calculations in table b of your student guide. when the speed of the bottle is 2 m/s, the ke is kg m2/s2. when the speed of the bottle is 3 m/s, the ke is kg m2/s2. when the speed of the bottle is 4 m/s, the ke is kg m2/s2. when the speed of the bottle is 5 m/s, the ke is kg m2/s2. when the speed of the bottle is 6 m/s, the ke is kg m2/s2
