Homework Statement
How would I go about finding the energy loss of a Pendulum from top (Ep) to Bot (Ek)
Mass= 2.0kg
Length= 0.38m
height= 0.05091m
theta= 30°
2. The attempt at a solution
I know that we could find Ep by going mgh (2.0kg)(9.81m/s)(0.05091m)=1.0J of Ep
But how would I calculate Ek at the bottom and the amount of energy loss from Ep to Ek due to friction?
