you are standing on roof of a building you have one stone and a stopwatch with you.how can you find height of the building
time the fall.
height=1/2 *9.8m/s^2 * time^2
To find the height of the building, you can use the stone and the stopwatch in the following steps:
1. Find an open space directly beneath the building's roof, where you can safely drop the stone without it hitting anything.
2. Start the stopwatch when you drop the stone from the roof.
3. Observe the time it takes for the stone to reach the ground. Stop the stopwatch when it hits the ground.
4. Use the equation for free-fall motion to calculate the time it takes for the stone to fall:
- h = 0.5 * g * t^2
where h is the height, g is the acceleration due to gravity (approximately 9.8 m/s^2), and t is the time it takes for the stone to fall.
5. Plug the measured time into the equation and solve for h:
- h = 0.5 * 9.8 * t^2
The resulting value for h will give you the approximate height of the building.
