## Question

###### At least one of the answers above is NOT correct:point) A 10 kilogram object suspended from the end of a vertically hanging spring stretches the spring 9.8 centimeters. At time 0 , the resulting mass-spring system is disturbed from its rest state by the force F(t) 90 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. 1000 Newtons meterFormulate the initial value problem for y(t) , where y(t)

At least one of the answers above is NOT correct: point) A 10 kilogram object suspended from the end of a vertically hanging spring stretches the spring 9.8 centimeters. At time 0 , the resulting mass-spring system is disturbed from its rest state by the force F(t) 90 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. 1000 Newtons meter Formulate the initial value problem for y(t) , where y(t) is the displacement of the object from its equilibrium rest state, measured positive in the downward direction: (Give your answer in terms of y, y' ,y",t.) Differential equation: -1OOy-9cos(8t) help (equations) Initial conditions: y(0) and y' (0) help_(numbers) Solve the initial value problem for y(t) y(t) 4(cos(8t)-cos(1Ot)) help (formulas) Plot the solution and determine the maximum excursion from equilibrium made by the object on the time interval 0 <t < 0 . If there is no such maximum_ enter NONE maximum excursion NONE meters help (numbers)
