Answer: The force constant k is 10600 kg/s^2
Step by step:
Use the law of energy conservation. When the elevator hits the spring, it has a certain kinetic and a potential energy. When the elevator reaches the point of still stand the kinetic and potential energies have been transformed to work performed by the elevator in the form of friction (brake clamp) and loading the spring.
Let us define the vertical height axis as having two points: h=2m at the point of elevator hitting the spring, and h=0m at the point of stopping.
The total energy at the point h=2m is:
The total energy at the point h=0m is:
The two Energy values are to be equal (by law of energy conservation), which allows us to determine the only unknown, namely the force constant k:
Answer: Their dna would be part of ares and possibly cause mutations in our bodys
Explanation:
We're going to multiply the time it took for you to hear thunder (3.5 seconds) by the speed of sound in air (340 m/s)
3.5 x 340 = 1190
The lightning bolt was 1,190 meters away.
We have that the cricket’s displacement is
From the Question we are told that
Start position 5 meter mark
It jumps to the 10 meter mark.
it jumps back to the 6 meter mark.
Generally the equation for cricket’s displacement. is mathematically given as

Answer:
<h2> 145km</h2>
Explanation:
The displacement is a vector quantity, it tells how far away from a point a distance or a destination is
given that the distance covered are
50. km, 30. km, and 65 km
the displacement is expressed as
= 50+30+65
=145km
We actually performed straight addition because in all the movement the antarctic explorers did not record any deviation from the initial direction, hence they maintained a linear movement from the beginning to the end
