Consider two frictionless inclined planes with the same vertical height. Plane $1$ makes an angle of $30\mathrm{.}0$ with the horizontal, and plane $2$ makes an angle of $50\mathrm{.}0$ with the horizontal. Mass m$1$ is placed at the top of plane $1,$ and mass m$2$ is placed at the top of plane $2.$ Both masses are released at the same time.
