Question

1. Rearrange the following equations for the selected variable PEelas kx2 for Ix for k T 2T 2. Some people modify cars to be much closer to the ground than when manufactured. Should they install stiffer springs? Explain your answer. 3. Pendulum clocks are made to run at the correct rate by adjusting the pendulum's length. Suppose you move from one city to another where the acceleration due to gravity is slightly greater, taking your pendulum clock with you, will you have to lengthen or shorten the pendulum to keep the correct time, other factors remaining constant? Explain your answer.
