i am not quite familiar with circular motion, is it possible to find this acceleration?

    |dw:1327329605977:dw| can we just simply put (4-1)/4?

    Oh, this is track sitting on earth under the acceleration of gravity?

    In which case acceleration is supplied by gravity, but they you need to scale it, depending on the angle the object makes to the vertical. If you draw a line from the center of the circle down to the bottom of the circle and measure angle \( \theta \) with respect to that line, then the acceleration due to the force of gravity acting on the mass is \[ g \sin \theta \] If you're interested in this more, have a look at this: http://ocw.mit.edu/courses/physics/8-01-physics-i-classical-mechanics-fall-1999/video-lectures/lecture-10/ The movement of bodies on a pendulum is very similar to that of movement of bodies on a spring.
