A Study on Gravity and Velocity in Free Fall
Question:
After a person bungee jumped off a cliff and had a velocity of 40 m/s two seconds after the jump, what was the final velocity five seconds after the jump?
Answer:
The speed after 2 seconds into the jump was 40 m/s. Since gravity causes velocity to increase by 9.8 m/s during free fall, the speed 5 seconds after the jump can be calculated as follows:
Speed 5 seconds after the jump = 40 + (3 * 9.8) = 69.4 m/s
Understanding Gravity and Velocity in Free Fall:
Gravity's Impact: All matter in the universe is influenced by the force of gravity, causing objects to be drawn towards each other. From subatomic particles to galaxy clusters, gravity affects objects of all sizes.
Velocity and Free Fall: When an object is in free fall, its velocity increases by approximately 9.8 m/s each second, accelerating due to the force of gravity.
Velocity as a Measure: The velocity of an object in motion indicates how rapidly its position is changing relative to a specific point of reference and is measured in a particular unit of time.
