Apendulum is used in a large clock. the pendulum has a mass of 2kg. if the pendulum is moving at a speed of 2.9 m/s when it reaches the lowest point on its path, what is the maximum height of the pendulum?

Answer : Maximum height of the pendulum is 0.43 m

Explanation :

Given that,

Mass of the pendulum, m = 2 kg

Speed of the pendulum, v = 2.9 m/s

When it reaches the lowest point on its path, the potential energy at the highest point is equal to the kinetic energy at the lowest point.

i.e.

h is the height of the pendulum.

Hence, this is the required solution.                              

as technology advances, new experiments often expose problems in accepted theories. c

another example of kinetic energy would be,

kinetic energy   >     moving energy
