Answer:
Kinetic energy
Explanation:
When an apple falls from a tree it has to do with the energy from gravity. Gravity energy turns into kinetic energy once its in motion.
Sorry if im wrong

Vf = Final velocity.
Vi = initial velocity
a = acceleration.
t = time
Vf = Vi + at
Vf = 0 + (2 m/s^2)(3s)
Vf = 6 m/s south
Answer
Given,
Time to hear the clap = 14.4 s
speed of the light = 3 x 10⁸ m/s
Speed of sound = 343 m/s
a) distance where lightning strike
D = s x t
D = 14.4 x 343
D = 4939.2 m
b) No, we do not need to know the value of speed of light. Because we need to calculate the distance where we hear the sound. To calculate that we need to know the speed of sound.
B because it is the only evidence that displays an effect from the field without contact
