¿Qué trabajo realiza una fuerza de 15N cuando desplaza un cuerpo 13m en la dirección en que se aplicó?

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?
