Answer :
Final answer:
The time it takes for the potato to start moving in a direction exactly below the horizontal is half of the total time of flight. The coordinates of the potato at this time can be calculated using the equations of motion.
Explanation:
In projectile motion, when an object is launched into the air, it follows a curved path under the influence of gravity. The motion can be divided into horizontal and vertical components. Initially, the object moves horizontally at a constant velocity, while vertically it experiences a downward acceleration due to gravity.
The time it takes for the object to start moving in a direction exactly below the horizontal is half of the total time of flight. This is because the object reaches its highest point at the midpoint of its trajectory, and from there it starts moving downward.
To find the time it takes for the object to reach this point, we can use the equation:
time = (2 * vertical velocity) / acceleration due to gravity
Once we have the time, we can calculate the coordinates of the potato at this time using the equations of motion.
