Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Determine the Direction Cosine Matrices N[C]B and B[C]N

A particle P of mass m = 3 kg arrives at point O with a horizontal velocity vo and starts rolling
down a circle with radius R = 3.5 m. The particle is attached to the point O by means of a linear
spring of stiffness k = 60 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 = {î, îy} be a fixed reference
frame as shown in the figure and let B = {b, by} be a reference frame attached to P so that ba
is tangent to the circular path and by is perpendicular to the circular path. For convenience, take

When Crates A and B of mass ma = 31 kg and mB = 78 kg are released from rest, Crate A moves to the right on a rough surface (u = 0.4 ). The force P = 20 Newtons is always acting on Crate B. The linear spring has a stiffness of k = 490 N and is initially stretched 0.4 meters before the system is released from rest. Neglect the mass of the pulleys and cables and neglect friction in the pulley bearings. Determine the work done by the weight of Crate B (in Joules) when Crate A has moved a distance of 0.8 meters to the right. Consider g = 10 m. 82 B

Deduce an expression for the velocity at which the ball will bounce back off the tabletop. On its way back, will the mass bounce back to its initial height? If it will not, where will the difference in energy go? Discuss mathematically! (Pls solve the question in detail with figure)

Express your answer in terms of the variables a, m, x, and the acceleration due to gravity g, if needed. Consider a hanging spring of negligible mass that does not obey Hooke's law. When the spring is pulled downward by a distance r, the spring exerts an upward force of magnitude ar, where a is a positive constant. Initially the hanging spring is relaxed (not extended). We then attach a block of mass m to the spring and release the block. The block stretches the spring as it falls (Figure 1). (a) How fast is the block moving when it has fallen a distance z, ?
