Apackage is projected up a 15° incline at a with an initial velocity of 8 m/s. knowing that the coefficient of kinetic friction between the package and the incline is 0.12, determine (a) the maximum distance d that the package will move up the incline, (b) the velocity of the package as it returns to its original position.

John's grandfather clock has a pendulum that keeps the seconds. the observed pattern of motion for three complete swings of the pendulum is shown. assuming that the pendulum starts at the right and moves toward the center first, predict the direction the pendulum will move next
