Question: A particle P moves along the spiral path r=(10/θ)ft, where θ is in radians.  Part A: If it maintains a constant speed of v=20ft/s, determine vr as functions of θ. Express your answer in terms of θ   Part B: If it maintains a constant speed of v=20ft/s, determine vθ as functions of θ. Express your answer in terms of θ   Part C:  If it maintains a constant speed of v=20ft/s, evaluate vr at θ=1rad. Express your answer to three significant figures and include the appropriate units.

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.
