Write the equation which will represent conservation of angular momentum.

For the rotation in two dimensions, both energy, and angular momentum is quantized.  Select one: True False

Find the constraint acceleration equation between block A and B (Assume all upper and down pulleys' centrals are horizontal).

a.) What is the angle, measured relative to the positive x-axis, of the load's acceleration? (The correct answer is: -10.219 degrees) Just need the steps to get there  b.) Three horses pull and guide a 132 kg payload down a river, exerting the forces shown in the figure, with F1 = 29 N, F2 = 38 N, F3 = 58 N, θ1 = 30°, and θ2 = 60°. What is the magnitude of the payload's acceleration? (The correct answer is: 0.7861 m/s^2)Just need the correct steps to get there

A particle P of mass m = 3 kg arrives at point O with a horizontal velocity and starts rolling down a circle with radius R = 1.5 m. The particle is attached to the point O by means of a linear spring of stiffness k = 50 N/m that is unstretched when the particle is at O. Assume that during the motion of P along the circle, the spring follows the circle. Let N = {x, ây} be a fixed reference frame as shown in the figure and let B = {bx, by} be a reference frame attached to P so that b is tangent to the circular path and by is perpendicular to the circular path. For convenience, take g = 10 m/s² in this question. ny ĤT IP
