# Two balls are launched at the same time from opposite sides of a \( 100 \) \( \text{m} \) wide canyon. Ball A is launched at \( 20 \) \( \text{m/s} \) at \( 45^{\circ} \) from the left side. Ball B is launched at \( 20 \) \( \text{m/s} \) at \( 45^{\circ} \) from the right side.

Two balls are launched at the same time from opposite sides of a \( 100 \) \( \text{m} \) wide and \(1000 ~\text{m}\) canyon. Ball A is launched at \( 20 \) \( \text{m/s} \) at \( 45^{\circ} \) from the left side. Ball B is launched at \( 20 \) \( \text{m/s} \) at \( 45^{\circ} \) from the right side.

**Part a)** Do the balls collide mid-air? *(3 points)*

**Part b)** If so, at what time and height? *(3 points)*

**Part c)** What is their horizontal separation \( 1.5 \) \( \text{s} \) after launch? *(3 points)*
