The potential energy of a particle is U = y2 siny. The force defined – InterviewSolution

1.	The potential energy of a particle is U = y2 siny. The force defined on this particle is F = \(-\frac{d U}{d y}\). Calculate the force
Answer» Given; U = y² sin y and F = \(-\frac{d U}{d y}\), F = ? ∴ F = \(-\frac{d U}{d y}=-\frac{d}{d y}\left(y^{2} \sin y\right)\) or F = - (2ysiny + y² cosy)
