ANSWER THIS CORRECTLY.
Order the following objects from LEAST potential energy to the GREATEST potential energy.
**Remember PE=mgh**
1. 2 kg mass at 60 m height
2. 20 kg mass at 50 m height
3. 40 kg mass at 2 m height
4. 5 kg mass at 5 m height
To order the objects from least to greatest potential energy, we need to calculate the potential energy for each object using the formula PE = mgh.
1) For the 2 kg mass at 60 m height:
PE = (2 kg) x (9.8 m/s^2) x (60 m) = 1176 J
2) For the 20 kg mass at 50 m height:
PE = (20 kg) x (9.8 m/s^2) x (50 m) = 9800 J
3) For the 40 kg mass at 2 m height:
PE = (40 kg) x (9.8 m/s^2) x (2 m) = 784 J
4) For the 5 kg mass at 5 m height:
PE = (5 kg) x (9.8 m/s^2) x (5 m) = 245 J
Therefore, the objects ordered from least to greatest potential energy are:
4) 5 kg mass at 5 m height (245 J)
3) 40 kg mass at 2 m height (784 J)
1) 2 kg mass at 60 m height (1176 J)
2) 20 kg mass at 50 m height (9800 J)
