Question

the total energy of the rubber band is 5 units. the rubber band is nudged off the table and falls. at a point during its fall, it has 3 units of kinetic energy. how many units of potential energy are there? 3 units 5 units 4 units 2 units

Explanation:

Step1: Recall energy conservation

Total energy = Kinetic energy + Potential energy. Let \( TE = 5 \) (total energy), \( KE = 3 \) (kinetic energy), and \( PE \) be potential energy. So \( TE=KE + PE \).

Step2: Solve for potential energy

Rearrange the formula: \( PE=TE - KE \). Substitute values: \( PE = 5 - 3 = 2 \).

Answer:

2 units
