1.	The string of a pendulum is 2.0m long. The bob is pulled sideways so that the string becomes horizontal and then the bobis released. What isthe speed with which the bob arrives at the lowest point ? Assume theat 10% of initial energy is dissipated against air resistance. Take g=10m//s^(2)
Answer» SOLUTION :`1/2 MV^(2)=90% ` of mg H `:.v=6m/s`
