Question 11: The force associated with the following potential energy U (x, y, z) = –kry² 23 %3D is the only force acting on a particle of mass m. Here, k is a constant. The particle is initially at rest and at the origin. Assuming that the particle is passing through position (x 1 meter, y = 1 meter, z = 2 meter), find the speed of the particle at that position.
