As this mechanical energy is associated with height, it would be "Potential Energy" in particular.
U = mgh
U = F.h
U = 1.5 * 4
U = 6 Joules
So, 6 J of energy is lost before it hits the ground.
Hope this helps!
Answer:
11.56066 m/s
Explanation:
m = Mass of person
v = Velocity of person = 13.4 m/s
g = Acceleration due to gravity = 9.81 m/s²
v' = Velocity of the person in the second
The kinetic and potential energy will balance each other at the surface

Height of the cliff is 9.15188 m
Let height of the fall be h' = 2.34 m

The speed of the person is 11.56066 m/s
Hello!
The best explanation is the new "experimental evidence", which occur with the help of new and improved technology. For this question, I suggest you to answer letter b).

Answer:
The average velocity is 0.15 m/s
Explanation:
Use the definition of average velocity as the distance traveled divided the time it took.
Since the movement was on the plane from the origin (0, 0) to the point (-30, 20) corresponding to 30 m west and 20 m north, we calculate the distance using the distance between two points on the plane:

Then the magnitude of the average velocity can be estimated via the quotient between distance divided time, but since the units required are meters per second, we first convert the four minute time into seconds: 4 * 60 = 240 seconds.
Then the average velocity becomes:
