Answer:
Mass of Bottle 0.125 kg then KE = 1 kg · m^2/s^2
Mass of Bottle 0.250 kg then KE = 2 kg · m^2/s^2
Mass of Bottle 0.375 kg then KE = 3 kg · m^2/s^2
Mass of Bottle 0.250 kg then KE = 4 kg · m^2/s^2
Explanation:
Plug in the mass (given in question) and then plug in the velocity (given as 4 m/s) into the equation KE = 1/2 mv^2 and evaluate
Example - Mass of Bottle 0.125 kg
Velocity 4 m/s
KE = 1/2 · mv^2
KE = 1/2 · 0.125 kg · 4 m/s^2
KE = 1 kg · m^2/s^2
