Question

An object is dropped from rest and takes 2.41 seconds to reach the ground below. From
what distance above the ground was it dropped? State this as a positive number and
assume it has proper SI Units.

Expert Solution

Step 1

The height from which the object was dropped can be determined by the following kinematics equation.

Here, u, a, and t represent the object’s initial velocity, the object’s acceleration, and the time, respectively.

Let the vertically downward motion be the motion’s positive direction.

The object is falling under the influence of the Earth’s gravity; thus, its acceleration is the same as the acceleration because of the Earth’s gravity.
