# An object of mass \(2 \, \text{kg}\) is thrown vertically downwards with an initial kinetic energy of \(100 \, \text{J}\). What is the distance fallen by the object at the instant when its kinetic energy has doubled?

An object of mass \(2 \, \text{kg}\) is thrown vertically downwards with an initial kinetic energy of \(100 \, \text{J}\). What is the distance fallen by the object at the instant when its kinetic energy has doubled?

- **A.** \(2.5 \, \text{m}\)
- **B.** \(5.0 \, \text{m}\)
- **C.** \(10 \, \text{m}\)
- **D.** \(14 \, \text{m}\)
