A 3.00-kgkg object is free to slide on a horizontal surface. Theobject is attached to a spring of spring constant 300 N/mN/m , andthe other end of the spring is attached to a wall. The object ispulled in the direction away from the wall until the spring isstretched 70.0 mmmm from its relaxed position. The object is notreleased from rest, but is instead given an initial velocity of2.50 m/sm/s away from the wall. Ignore friction.
a) Determine the energy of the oscillating system.
b) Select the correct equation for the object's position xx as afunction of time. Suppose that x=0x=0 is the equilibrium positionand the direction away from the wall is the positive direction ofxx.
