Explanation Given: The variable force applied to move the object is 5 x − 2 . The object is moved from a location x = 1 ft to x = 10 ft. Calculation: Consider the variable force applied on the object as f ( x ) = 5 x − 2 (1) Find the work done by the moving object from 1 to 10 ft using the expression. W = lim n → ∞ ∑ i = 1 n f ( x i ∗ ) Δ x = ∫ a b f ( x ) d x (2) Substitute 5 x − 2 for f ( x ) , 1 for a and 10 for b in Equation (2)

5. Suppose that a mass of 5 stretches a spring 10. The mass is acted on by an external force of F(t)=10 sin () and moves in a medium that gives a damping coefficient of ½. If the mass is set in motion with an initial velocity of 3 and is stretched initially to a length of 5. (I purposefully removed the units- don't worry about them. Assume no conversions are needed.) a) Find the equation for the displacement of the spring mass at time t. b) Write the equation for the displacement of the spring mass in phase-mode form. c) Characterize the damping of the spring mass system as overdamped, underdamped or critically damped.
