Question

the total energy of the rubber band is 3 units. at a certain point after the rubber band is released, its kinetic energy is 2 units. how many units of potential energy are there? 0 units 1 unit 2 units 3 units

Explanation:

Step1: Recall the energy conservation principle

The total energy of a system (here, the rubber band) is the sum of its kinetic energy (\(KE\)) and potential energy (\(PE\)). So, \(Total\ Energy = KE + PE\).

Step2: Substitute the known values

We know the total energy is 3 units and the kinetic energy is 2 units. Rearranging the formula to solve for potential energy: \(PE = Total\ Energy - KE\). Substituting the values, we get \(PE = 3 - 2\).

Step3: Calculate the potential energy

\(3 - 2 = 1\).

Answer:

B. 1 unit
