5. Position when spring is unstrained www Xf xo In the figure above the mass attached to the spring is 0.2 kg. The spring's constant is 40 N/m. The mass is stretched to a position of 0.3 m and released. The final position is 0.1m. 1. Find the change in potential energy of the system. 2. What is the work done by the spring? A spring whose spring constant is 120 N/m has a 0.1 kg block attached to it. The spring and mass sit on a horizontal frictionless surface. The block is pulled 0.2 m and released. 1. Find the frequency of the oscillations 2. Find the period of the oscillations 3. Find the angular frequency of the oscillations (0) 4. Find the amplitude of the oscillations 5. Find the maximum velocity of the block 6. Find the maximum acceleration of the block 7. Write expressions for the displacement, velocity and acceleration as functions of time.
