To calculate the time it takes for the hammer to reach the ground, we can use the equation of motion:
h = (1/2) * g * t^2
where:
h = height of the building = 180m
g = acceleration due to gravity = 9.8m/s^2
t = time taken to reach the ground (unknown)
Rearranging the equation, we get:
t^2 = (2 * h) / g
Plugging in the given values:
t^2 = (2 * 180) / 9.8
t^2 = 36.73
t ≈ √36.73
t ≈ 6.06 seconds
Therefore, it takes approximately 6.06 seconds for the hammer to reach the ground.
