A group of biomolecules acts like a spring with spring constant 1000 N/m and is initially stretched to 0.01 mm from its resting length. When released, it oscillates with a period of 0.4 ms. Write your answer using TWO decimal places! Do NOT include units. You must include a leading zero in your answer if appropriate (e.g., 0.18). (a) What force (in newtons) initially stretched the biomolecules? (2 marks) Answer (b) What will be the potential energy stored in the same biomolecules at full
