A body when projected vertically up from ground clovers a total distance D during the time of its flight t. If there were no gravity. The distance covered by it during the same time is equal to

Options

A. 0
B. D
C. 2D
D. 4D

Explanation

To solve the problem, we need to find the distance covered by a body projected vertically upward during the time of flight \( t \) if there were no gravity. Let's break it down step by step.

### Step 1: Understand the motion of the body
When a body is projected vertically upward, it travels upward until it reaches its maximum height and then falls back down to the ground. The total distance covered during this entire flight is the sum of the distance traveled upward and the distance traveled downward.

### Step 2: Define the total distance covered
Let the total distance covered by the body during the time of flight \( t \) be \( D \). Since the body goes up and comes back down, the total distance can be expressed as:
\[
