KEPLER'S LAW Activity 3. Think Critically Solve the following in a clean sheet of paper. Show your solution and box your final answer. 1. A 70-g body is attached at the end of a hanging spring with a spring constant of 3,500 dynes/cm. It is displaced 15 cm from its equilibrium position and then released. a. calculate the period (T); b. find the maximum acceleration of the body; and c. find the acceleration of the body when it is 22 cm from the equilibrium position. 2. A string of a pendulum has a length of 1.2 m and has a period of 2.45. a. find the value of g at a point of the pendulum; and b. if the same pendulum is brought to another place where the value of g is 9.83 m/s, what is the period of the pendulum at that place? 3. A body is pivoted so that its center of gravity is 2.5 m from the axis of rotation. The body's radius of gyration is 28 cm. The body acts like a physical pendulum. Find the period of vibration of the body
