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

Each equation represents a linear relationship. Examine each and determine the slope and y- intercept
marysya [2.9K]

Answer:

Slope is -3/7. Y intercept is 250/7.

Step-by-step explanation:

Since they asking for the slope and y intercept, let put it in slope intercept form.

y = mx + b

where m is the slope and b is the y intercept.

The equation given is in standard form so we will convert it to slope intercept.

3x + 7y = 250

7y = 250 - 3x

y =  \frac{250}{7}  -  \frac{3}{7} x

y =  -  \frac{3}{7} x +  \frac{250}{7}

The slope is -3/7

The y intercept is 250/7
