An apple dropped from an apple tree. the height of the tree was 2.5 m. what was the final speed of the apple right before landing? the correct answer is 7 m/s. i have no clue pls

The correct answer to the question is : 7 m/s.

EXPLANATION:

As per the question, the apple is at a height h = 2.5 m.

The initial velocity of the apple u = 0

We are asked to calculate the final velocity [ v ] of the apple before touching the ground.

As the apple is falling under gravity, then the acceleration produced on the apple is nothing else than acceleration due to gravity.

Hence, acceleration a = g =

From equation of kinematics , we know that -

                              ⇒  

                               ⇒

                               ⇒

                              ⇒  

                               ⇒                     [ans]

Hence, the final velocity is 7 m/s.

answer; /// i believe that the correct answer is (c)

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
