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
(-1,-4) is where the equations Y=4x and x+y=-5 intersect.
Answer:
f ÷ 10
Step-by-step explanation:
We want to write an expression
divided by means the number or variable before comes first, then the divided by symbol, then what comes after
f ÷ 10
Answer:
Yes your friend is correct.
Step-by-step explanation:
This can become very complex when trying to explain but essentially, opposite angles like angle 4 and 6 or the 103 degree and angle 2 would have the same angle measurement. Since angle 2 and 6 are on the same straight line with lines a and b being parallel, we know that that angle 2 and 6 are equal. Since we know that angle 2 and the 103 degree angle are equivalent, we can conquer that angle 6 equals 103 degrees.
