.
Answer in units of m/s.

Answer 1

Answer: The apple will hit the ground at a speed of approximately 13.2 m/s.

Explanation:

To calculate the speed at which the apple hits the ground, we can use the following equation: v² = u² + 2as

where:

v = the final velocity (the speed at which the apple hits the ground)

u = the initial velocity (which is zero in this case)

a = the acceleration (which is -9.8 m/s² in this case)

s = the distance traveled (which is 8.83 m in this case)

Substituting these values into the equation, we get:

v² = 0² + 2 * -9.8 * 8.83

v² = -173.14

v = √-173.14

v ≈ 13.2 m/s

Note that the acceleration due to gravity is negative in this case because it is acting in the opposite direction to the apple's motion.
