The formula for calculating kinetic energy is KE = 0.5 * mass * speed^2.
Calculating the kinetic energy for each object:
1. 10 kg moving at 2 m/s:
KE = 0.5 * 10 * 2^2 = 20 Joules
2. 5 kg moving at 2 m/s:
KE = 0.5 * 5 * 2^2 = 10 Joules
3. 2 kg moving at 2 m/s:
KE = 0.5 * 2 * 2^2 = 4 Joules
4. 10 kg moving at 5 m/s:
KE = 0.5 * 10 * 5^2 = 125 Joules
Therefore, the object with the greatest amount of kinetic energy is the 10 kg object moving at 5 m/s with 125 Joules of kinetic energy.
Based on the mass and speed data, which object will have the greatest amount of kinetic energy?
10 kg moving at 2 m/s
5 kg moving at 2 m/s
2 kg moving at 2 m/s
10 kg moving at 5 m/s
