_ _______ _ A horizontal mass spring system consists of a block sliding on a 'ictionless surface attached to a spring. The other end of the spring is rmly attached to a wall. The spring has spring constant 324 N/m and the block has mass 4 kg. The mass is pulled 5 cm to the right and then is released. (a) Calculate the angular frequency of the oscillator. 1 (b) Calculate the energy of the oscillator just as it is released. 2 (0) Write an equation that describes the motion of the block as a function of time. 2 (d) The same mass and spring system is then hung vertically from the ceiling. Calculate the period of the resulting simple hannonic oscillator. N (e) In a separate problem, a car driving 18 kin/hr drives into a stiff horizontal spring attached to a solid wall. The spring compresses 1.25 m before the car stops. Calculate the time it takes for the car to come to a stop after it rst makes contact with the spring. 0.)
