A bridge that was 10.4 m long has been washed out by the rain several days ago. How fast must a car be going to successfully jump the stream? Although the road is level on both sides of the bridge, the road on the far side is 1.5 m lower than the road on this side.

Question
**Physics Problem: Calculating Jump Speed Needed**

A bridge that was 10.4 meters long has been washed out by the rain several days ago. How fast must a car be going to successfully jump the stream? Although the road is level on both sides of the bridge, the road on the far side is 1.5 meters lower than the road on this side.

**Discussion:**

- We need to determine the initial horizontal velocity required for a car to clear a distance of 10.4 meters, given a vertical drop of 1.5 meters on the landing side.
- Assuming no air resistance, use projectile motion equations to solve for the horizontal velocity.

**Key Physics Concepts:**

- The horizontal motion is uniform, while the vertical motion is affected by gravity.
- The time for the car to fall 1.5 meters vertically will determine the time available to cover the horizontal distance.
