A ball is dropped from a roof and takes 3.0 s to reach the ground. Calculate the elevation of the roof above the ground in meters.
Yes
Solve: an iron ball is dropped from the roof and it takes 3second to reach the ground.calculate the elevation of the roof above the ground.
Yes
To calculate the elevation of the roof above the ground, we can use the formula for the distance traveled by a falling object:
d = (1/2) * g * t^2
where:
d = distance traveled (elevation of the roof)
g = acceleration due to gravity (approximately 9.8 m/s^2)
t = time taken for the ball to reach the ground (3.0 s in this case)
Substituting the given values into the formula:
d = (1/2) * 9.8 m/s^2 * (3.0 s)^2
d = 14.7 m
The elevation of the roof above the ground is 14.7 meters.
h=1/2 g t^2 solve for h
h = 1/2 (-9.81) (3^2)
h = -44.14 meters
