10. A rock is dropped straight off a bridge that is 50 meters above the ground and falls at a speed of 10 m/sec. Another person is 7 meters away on the same bridge. At what rate is the distance between the rock and the second person increasing just as the rock hits the ground? Rock Dropped Here 7 meters Person Find Rate This Distance Changing Rock

Step 1
The rock falls from a height of 50 meters. Using the formula for free fall \( h = \frac{1}{2} g t^2 \), where \( h = 50 \) meters and \( g = 9.8 \, \text{m/s}^2 \), solve for \( t \). Show more…
