# A 1.0 kg lump of clay is sliding to the right on a frictionless surface with speed of [katex] 2 \, \{m/s} [/katex]. It collides head-on and sticks to a 0.5 kg metal sphere that is sliding to the left with speed [katex] 4\, \{m/s}[/katex]. What is the kinetic energy of the combined objects after the collision?

A \( 1.0 \, \text{kg} \) lump of clay is sliding to the right on a frictionless surface with a speed of \( 2 \, \text{m/s} \). It collides head-on and sticks to a \( 0.5 \, \text{kg} \) metal sphere that is sliding to the left with a speed of \( 4 \, \text{m/s} \). What is the kinetic energy of the combined objects after the collision?

- **A.** \(6 \, \text{J}\)
- **B.** \(4 \, \text{J}\)
- **C.** \(2 \, \text{J}\)
- **D.** \(0 \, \text{J}\)
