AI Generated Solution

To solve the problem of finding the height of the tower from which a particle is dropped, we can use the equations of motion under uniform acceleration due to gravity. Here’s a step-by-step solution: ### Step 1: Understand the Problem A particle is dropped from the top of a tower and covers a distance of 40 m in the last 2 seconds of its fall. We need to find the total height of the tower. ### Step 2: Use the Equation of Motion For an object in free fall, the distance covered in the nth second can be expressed as: \[ ...
