Homework Statement
A clock’s pendulum is 60 cm long with a bob at the end of mass 500 g. Determine the maximum tension in the pendulum rod when the bob is
b) swinging at a speed of 2.4 m/s
Homework Equations
v^2 / r = ac
The Attempt at a Solution
9.8m/s^2 = g
(2.4)^2 / 0.6 = 9.6m/s^2
9.8 * 0.5 = 4.9N
9.6 * 0.5 = 4.8N
Fnet = 4.9 - 4.8 = 0.1 N
What am I doing wrong? ._.
Thank you.
Okay guys I looked t it from another perspective and ended up wit the right answer.
I added the force of gravity and the tension going up.
But here's a small question. Why do we have to add them? Are they not cancelling each other out? Or is it because the pendulum is balanced ? o.o
So we add both tensions?
