# A classical mechanics problem by manish kumar singh

A pendulum bob has a speed of $$3 \text{ m/s}$$ while passing through its lowest position. What is its speed when it makes an angle of 60 degree with vertical?

Take the length of the pendulum to be $$0.5 \text{ m}$$.
Take $$g=10\text{ m/s}^2$$.
