A pendulum Bob has a mass of 0.750 kg and is on a pendulum arm of lenght 1.00 m

Question

A pendulum Bob has a mass of 0.750 kg and is on a pendulum arm of lenght 1.00 m . The pendulum is pulled back so that the arm makes an angle of 60 degree from the vertical and is then released. What is speed of the mass when it reaches its lowest point? A pendulum Bob has a mass of 0.750 kg and is on a pendulum arm of lenght 1.00 m .

Explanation / Answer

potential energy = kinetic energy

0.5*m*v*v = m*9.8* 1 *(1-cos60)

required v = 3.13 m/s
