Answer:
Muscle size and training specifiicty
Explanation:
It depends on all other factors such as anatomy and psychology, muscle fiber recruitment, motor pattern development and muscle memory but to increase modifiable strength, size plays no big role.
Answer:
110 meters is the distance where they will intersect
Explanation:
given,
liquid density = 1900 kg/m³
distance of upper hole = 19 m
distance of lower hole = 117 m
acceleration due to gravity = 9.8 m/s²
the speed at each point
for upper hole
v = 19.29 m/s
lower hole
v = 47.88 m/s
The path for each is parabolic
x = v t
we get
upper hole
lower hole
y for upper hole = 80 + y for lower hole


x = 109.32 meters
110 meters is the distance where they will intersect
As the boulder falls off the cliff, the gravitational potential energy that the boulder has is converted into kinetic energy. If you do the calculations, you will see that the kinetic energy the boulder has is equal to the gravitational potential energy it had before it fell off a cliff.
