GR0177 First Problem Help

Post by paklun123 » Fri Aug 10, 2007 7:45 pm

Can someone explain the first problem in GR0177 to me? I am confused as to how to find the direction of the acceleration of the pendulum.

Thanks

Pak

There's the force of gravity and the tension from the string. Add them together to get the net force.
