An object is released from rest at a height of 25m. Calculate the time it takes to fall to the ground. [g = 10ms-2]
Question 1 Report
An object is released from rest at a height of 25m. Calculate the time it takes to fall to the ground. [g = 10ms-2]
Answer Details
The time taken for an object to fall freely from a height h can be calculated using the formula:
t = sqrt(2h/g)
Where t is the time taken, h is the height and g is the acceleration due to gravity.
Substituting the values given, we get:
t = sqrt(2 x 25 / 10) = sqrt(5) = 2.24s
Therefore, the time it takes to fall to the ground is 2.24s.
The correct option is (d).
