Energy Transformation is the process of changing one form of energy to another form...
There is no connection there that I can think of.
Answer:
The elevator's velocity after 6 seconds is 3.189m/s
Explanation:
Using Newton's 2nd law:Fnet = ma
Mg - N = ma
Where m = mass
N = normal force
a = acceleration
g = acceleration due to gravity
Substituting the given values and finding acceleration
(95kg)(9.8m/s^2) - 830N = 95kg x a
a = (931 -830) / 95
a = 101/95
a = 1.063m/s^2
After 3 seconds, the weight 0f the person is equal to the actual weight of the person, thus the elevator will be moving at a constant velocity.
Using kinematic equation:
V = u + at
Where V = final velocity
U = initial velocity = 0
a = acceleration
t = time
V = 0 + 1.063 × 3
V = 3.189m/s
This velocity does not change . The elevator travels the test of the time at the same velocity. Therefore,the velocity at 6 seconds = 3.189m/s
When it falls though a vaccum,it is subjected to only one external force,the gravitational force.
