A rock falls off a bridge and hits the water 8 seconds later. How high is the bridge? A rock falls off a bridge and hits the water 8 seconds later. How high is the bridge?
The Brooklyn Bridge clears the water below it by 135 feet (41 m) at mid-span.
The height of the bridge can be calculated using the formula: distance = 0.5 * acceleration due to gravity * time^2. Given that the rock takes 8 seconds to hit the water, the height of the bridge would be approximately 313.6 meters.
A+ the answer is 313.6
The speed at which the rock will strike the water will be approximately 15.6 m/s. This can be calculated using the formula for free fall with an initial velocity of 0 m/s and height of 25 meters.
The gravitational potential energy of the rock at the edge of the bridge is converted to kinetic energy as it falls. Use the formula for gravitational potential energy (mgh) to find the potential energy at the top, then equate that energy to the kinetic energy (1/2 * m * v^2) just before impact to solve for the final velocity. Finally, use this velocity in the kinetic energy formula to calculate the kinetic energy just as it hits the water.

it is an enormous 59 meters off water level
The Humber Bridge, located in the UK, has a main span that is approximately 155 meters (509 feet) above the water at high tide. The overall height of the bridge's towers reaches about 210 meters (689 feet) above the water level. The bridge is one of the longest suspension bridges in the world, connecting Hull and the East Riding of Yorkshire.
The height of the main towers of the Mackinac Bridge above the water is 552 feet.
The Akashi Kaikyō Bridge, also known as the Pearl Bridge, spans 3,911 meters (12,831 feet) and is the longest suspension bridge in the world. Its main span measures 1,991 meters (6,532 feet), and the bridge towers rise to a height of 282.8 meters (928 feet) above the water. The bridge was completed in 1995 and connects the city of Kobe on Honshu with Awaji Island.
I swam below the bridge I see fish below the bridge place the ball below the bottom shelf plese complete all answers below that picture I am writting this sentence below the one above it. I loked below my feet to the water
