A pendulum has a velocity of 2.5 m/s at the bottom of its swing. Using the law of conservation of energy, what is the maximum height of the pendulum's swing if there is no friction acting on it?

The maximum height of the pendulum's swing is 0.32 m

Explanation:

The Principle Of Conservation Of Mechanical Energy

In the absence of friction, the total mechanical energy is conserved. That means that

Em=U+K is constant, being U the potential energy and K the kinetic energy

U=mgh

At the bottom of the swing, the pendulum has zero potential energy but its kinetic energy is at maximum. At the top of the swing, the pendulum has zero kinetic energy and the potential energy is at maximum.

Thus, applying the principle of conservation of mechanical energy:

Simplifying by m:

Solving for h:

Substituting:

h = 0.32 m

The maximum heigth of the pendulum's swing is 0.32 m

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

pretty sure it's false
