# What angle will the string make with the vertical?

A light string carrying a small bob of mass $$5\times10^{-2}\text{ kg}$$ hangs from the roof of a moving vehicle. The vehicle moves down an incline making an angle of $$30^\circ$$ with the horizontal with a constant acceleration of $$3\text{ m/s}^2$$.

To the nearest degree, what angle will the string make with the vertical?
