please explain wedge plus pulley constraint relation.
The total energy of a simple harmonic oscillator is 0.8 erg. What is its kinetic energy when it is midway between an extreme position and mean position?
As a 10 kilogram mass on the end of a spring passes through its equilibrium position, the kinetic energy of the mass is 20 joules. The speed of the mass is: a) 2.0 meters per
