# A child of mass \(m\) starts from rest at the top of a frictionless playground slide of height \(h\) and reaches the bottom with speed \(v\). The child then moves to a much taller frictionless slide and starts from rest at a height \(4h\) above the ground. Which of the following is the speed of the child at the bottom of the second slide?

A child of mass \(m\) starts from rest at the top of a frictionless playground slide of height \(h\) and reaches the bottom with speed \(v\). The child then moves to a much taller frictionless slide and starts from rest at a height \(4h\) above the ground. Which of the following is the speed of the child at the bottom of the second slide?

- **A.** \( \dfrac{1}{2}v \)
- **B.** \( 2v \)
- **C.** \( 4v \)
- **D.** \( 16v \)
