The image shows a pendulum that is released from rest at point a. shari tells her friend that no energy transformation occurs as the pendulum swings between point b and point d.
what is the best response that shari’s friend could make?
she could agree with shari because the pendulum is at the same height and would have the same gravitational potential energy at both positions.
she could agree with shari because the pendulum has the same amount of mechanical energy throughout its swing.
she could disagree with shari because the pendulum converts kinetic energy into gravitational potential energy, then back into kinetic energy.
she could disagree with shari because the pendulum converts gravitational potential energy into kinetic energy, then back into gravitational potential energy.

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
