Problem 33P

A 5.76-kg rock is dropped and allowed to fall freely. Find the initial kinetic energy, the final kinetic energy, and the change in kinetic energy for (a) the first 2.00 m of fall and (b) the second 2.00 m of fall.

Step-by-Step Solution:

Solution 33P

Step 1 of 4

Here we need to find the initial kinetic energy, final kinetic energy and the change in kinetic energy.

The mass of the rock is: .

Initially the kinetic energy was zero as the stone was not released.

After falling for 2 meters,

-------------------(!)

       .

So, the kinetic energy will be,

   

    .
