Homework Statement


A pendulum swinging in a circular arc under the influence of gravity has both centripetal and tangential components of acceleration. (a) If the pendulum bob has a speed of 2.7m/s when the cord makes an angle of [tex]\Theta[/tex] =15 deg with the vertical, what are the magnitudes of the components at this time? (b) where is the centripetal acceleration a maximum? What is the value of the tangential acceleration at that location?

Length of the pendulum equals 0.75m

Homework Equations


ac=v^2/r

at=r[tex]\alpha[/tex]


The Attempt at a Solution



So I need to find the magnitude of ac, a, and at.

I have a Length, an angle, speed and gravity.

ac=2.7m/s^2/0.75
at=0.75(?)
a=?
