Explanation Given Information: The expression is x 2 − 25 = x 2 − 25 = x − 5 . Explanation: Consider the expression x 2 − 25 = x 2 − 25 = x − 5 The square root of any positive number has two roots one is positive and other is negative. Calculation: The radicand of expression x 2 − 25 is simplified as follows. x 2 − 25 = ( x − 5 ) ( x + 5 ) = ( x − 5 ) ( x + 5 ) The radicand of x 2 and 25 is perfect square roots and is further simplified as follows

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. Explain how you know. D.E. for Spring Mass Systems k m* g = kLo y" +—y' + — —±y = —±F(t), y(0) = yo, y'(0) = vo m 2 A₁ = √c₁² + C₂² Q = tan-1
