# Ballistic pendulum

A bullet of mass $$20~g$$ travelling horizontally at $$100~m/s$$ embeds itself in the center of a block of mass $$1~kg$$ which is suspended by light vertical string $$1~m$$ in length. Calculate the maximum inclination of the string to the vertical in degrees.

Details and assumptions

• The acceleration of gravity is $$-9.8~m/s^2$$.
