  • Calculating Velocity in Free Fall: A Step-by-Step Guide
    Here's how to solve this problem:

    Understanding Free Fall

    * Acceleration due to gravity: In free fall, objects accelerate downward due to gravity at approximately 9.8 m/s². This means their velocity increases by 9.8 m/s every second.

    Calculations

    1. Initial Velocity: We assume the object starts from rest, so its initial velocity (v₀) is 0 m/s.

    2. Time: The object falls for 0.10 seconds (t = 0.10 s).

    3. Final Velocity: We can use the following equation to find the final velocity (v):

    v = v₀ + at

    v = 0 + (9.8 m/s²) * (0.10 s)

    v = 0.98 m/s

    Answer

    The correct answer is A) 0.98 m downward.

    Important Note: The negative sign isn't strictly necessary in this case because we've already specified "downward." However, if you're using a coordinate system where downward is negative, the velocity would be -0.98 m/s.
