# Two identical metal balls are being held side by side at the top of a ramp. Alex lets one ball, \( A \), start rolling down the hill. A few seconds later, Alex’s partner, Bob, starts the second ball, \( B \), down the hill by giving it a push.

Two identical metal balls are being held side by side at the top of a ramp. Alex lets one ball, \( A \), start rolling down the hill. A few seconds later, Alex’s partner, Bob, starts the second ball, \( B \), down the hill by giving it a **push**. Ball \( B \) rolls down an identical, parallel path to the first ball and passes it. At the instant ball \( B \) passes ball \( A \) (select all that apply):

- **A.** It has traveled the same distance and has the same velocity as \( A \).
- **B.** It has traveled the same distance and has the same acceleration as \( A \).
- **C.** It has the same displacement and the same velocity as \( A \).
- **D.** It has the same displacement and the same acceleration as \( A \).
