Ive been trying to solve this problem for 2 hours now..
Suppose a weight is set in motion from a position 3 centimeters below the equilibrium position and with a downward velocity of 4 centimeters per second. (please note that the vertical number line used for position is upside down. This is a conversion from physics and it means that position below equilibrium actually correspond to a positive value.) Assume that spring stiffness and mass of the weight mean that w=2 for this system.
Write the function x(t) that gives the position of the weight as a function of time t in seconds. (Your function should consist of a sine term and a cosine term)
