Final answer:
To find the final velocity of an apple that fell from rest for 1.1 seconds, we use the formula Vf = Vi + (a * t), yielding a final velocity of approximately 10.78 m/s.
Step-by-step explanation:
The final velocity of an apple that a person drops after taking a bite. Because the apple started from rest and was subject to acceleration due to gravity, we can calculate its final velocity with the following kinematic equation:
Vf = Vi + (a * t)
Where:
Vf is the final velocity
Vi is the initial velocity (which is 0 m/s in this case, as the apple was dropped from rest)
a is the acceleration due to gravity (9.8 m/s²)
t is the time the apple was falling (1.1 seconds)
Substituting the known values into the equation, we get:
Vf = 0 + (9.8 m/s² * 1.1 s) = 10.78 m/s
Therefore, the apple's final velocity when it hit the ground was approximately 10.78 m/s.
