# A baseball is seen to pass upward by a window with a vertical speed of \( 14 \) \( \text{m/s} \). If the ball was thrown by a person \( 18 \) \( \text{m} \) below on the street, determine the following.

A baseball is seen to pass upward by a window with a vertical speed of \( 14 \) \( \text{m/s} \). If the ball was thrown by a person \( 18 \) \( \text{m} \) below on the street, determine the following.

**Part a)** What was its initial speed? *(3 points)*

**Part b)** What altitude does it reach? *(3 points)*

**Part c)** When was it thrown? (Hint: find the time of the rock, between reaching the window and leaving the person’s hand) *(3 points)*

**Part d)** When does it reach the street again? *(3 points)*
