The sphere of mass m1 = 5 kg falls from a height H = 1.4 m onto the homogeneous board of negligible mass. The board can rotate around a horizontal axis passing through point O, and a body of mass m2 = 3.9 kg is placed on it at a distance b = 1 m from the axis of rotation. The collision is perfectly inelastic. How high does the body of mass m2 rise after the collision (in m) if a = 0.5 m?

- Question 1 A particle P of mass m = 1 kg arrives at point O with a horizontal velocity Uo and starts rolling do a circle with radius R = 1.5 m. The particle is attached to the point O by means of a linear spring stiffness k = 65 N/m that is unstretched when the particle is at O. Assume that during the motion P along the circle, the spring follows the circle. Let N = {nx, ny} be a fixed reference frame as shown the figure and let B = {bx, by} be a reference frame attached to P so that bx is tanger the circular path and by is perpendicular to the circular path.

Each step is of uniform height d. The mass of each object is a multiple of the base mass m: object1 has mass 4.00m, object 2 has mass 1.96m, and object 3 has mass m. When the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. If the objects are then relocated as shown, what is the new total potential energy of the system? Each answer requires the numerical coefficient to an 2 algebraic expression. Each algebraic expression is given using some combination of the variables m, g, and d, where g is the acceleration due to gravity. Enter only the numerical coefficient.
