1) based on this graph of force vs. extension for a certain spring, what should be the hooke's law constant (or spring constant)?

show the full calculation using data from the figure, and report the answer in n/m.

2) suppose a 250 g mass was hung from the spring in the previous question. what would be the extension of the spring when it is in equilibrium and at rest?

write the equation needed to answer this question and the solve for the extension, recording the answer in either m or cm.

3) now the 250 g mass hanging from the spring in the previous question is pulled down an extra 10 cm and released. what would be the period and the counting frequency of the oscillations?

once again, begin with an equation and show the steps needed to find the answers.

Find the net torque on the wheel in the figure below about the axle through o perpendicular to the page, taking a = 9.00 cm and b = 27.0 cm. (indicate the direction with the sign of your answer. assume that the positive direction is counterclockwise.) n · m a wheel rotating about an axle is approximated as two concentric circles with the center defined to be o. the radius of the inner circle is a and the radius of the outer circle is b. three arrows representing individual forces are as follows. an arrow labeled 12.0 n acts on the top left of the inner circle, and points down and to the left at an angle of 30.0° below the horizontal. an arrow labeled 10.0 n acts on the top of the outer circle and points to the right. an arrow labeled 9.00 n acts on the right of the outer circle and points down.
