The absolute value shows the distance away from 0 (sea level), so the positive integer would be 282 ft, because it is the distance away from zero which is always positive
Full Question
A 10 kilogram object suspended from the end of a vertically hanging spring stretches the spring 9.8 centimeters. At time t = 0, the resulting mass—spring system is disturbed from its rest state by the force F (t) = 20 cos(8t). The force F (t) is expressed in Newtons and is positive in the downward direction, and time is measured in seconds.
Determine the spring constant k.
Answer:
Spring Constant = 1000Nm^-1
Step-by-step explanation:
Given
Mass = 10kg
Spring Extension = 9.8cm
Spring Constant K = Force/Extension
Force = Mass * Acceleration
Force = 10 * 9.8 = 9.8N
Spring Extension = 9.8 cm = 9.8 /100 = 0.098 m
Spring constant = 98 / 0.098
Spring Constant = 1000Nm^-1
Answer:
Step-by-step explanation:
Jared wrote the equation as,
k + (k + 1) + (k + 2) = 4k
Solution for k will be,
3k + 3 = 4k
4k - 3k = 3
k = 3
For k = 3, consecutive numbers will be → 3, 4, 5
Jared did not get the correct answer.Solution to this equation is k = 3, giving 3, 4, and 5 as three integers. However, 3 and 5 are not even integers. He should have used the equation k + (k + 2) + (k + 4) = 4k, which gives k = 6 and the correct answer is 6, 8, 10.
Answer:
3.4
Step-by-step explanation:
the answer would be 3.4
Since an isosceles triangle has two angles that are the same, and one different, the 120 degrees would be the different one. 180-120= 60 degrees 60/2=30 degrees
