SUMMARY
To calculate the height of the bridge from which Bill kicks a stone, use the horizontal velocity of 3.5 m/s and the horizontal distance of 5.4 m. The time taken for the stone to travel horizontally can be calculated using the formula time = distance/velocity, resulting in a time of approximately 1.54 seconds. During this time, the stone falls under the influence of gravity, allowing the height of the bridge to be determined using the equation for free fall: height = 0.5 * g * t², where g is 9.81 m/s². If the stone is kicked harder, the horizontal velocity increases, but the time to fall remains unchanged as it is solely dependent on the height of the bridge and gravitational acceleration.
