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: The answer is $152.25
Step-by-step explanation:
First you multiply 0.07 by 163.71 to get 11.4597.
The you subtract 163.71 from 11.4597.
Then that's your answer. I hope this helped!
Answer:
= 
= 
Step-by-step explanation:
triangle ADE and triangle ABC are similar
therefore, the ratio of their corresponding sides are equal
Let the line segment BD be x, then sin A = x/15
or, x = 15sinA
