* Gravity's Role: The velocity of a dropped object is affected by gravity. We need to know the acceleration due to gravity (approximately 9.8 m/s² on Earth).
* Initial Velocity: Is the object simply dropped (meaning it starts from rest, with an initial velocity of 0 m/s)? Or does it have an initial downward or upward velocity?
Here's how to calculate the velocity:
1. If the object is simply dropped (initial velocity = 0 m/s):
* Use the equation: v = g*t
* v = final velocity
* g = acceleration due to gravity (9.8 m/s²)
* t = time (3.0 seconds)
* Plug in the values: v = (9.8 m/s²) * (3.0 s) = 29.4 m/s
2. If the object has an initial velocity (v₀):
* Use the equation: v = v₀ + g*t
* v₀ = initial velocity
* g = acceleration due to gravity (9.8 m/s²)
* t = time (3.0 seconds)
Please provide the initial velocity if the object is not simply dropped, and I can calculate the final velocity for you.
