A Pendulum of mass 0.7kg is swinging . The maximum speed of the pendulum, where the

pendulum's position is at it's lowest, is 2.0ms-1. Calculate the maximum kinetic energy of

the pendulum and the maximum gravitational potential energy of the pendulum as it is at its greatest height.

ok, youre understood, sorry yea first time using this ;x

Relevant equations:

Ek ( Kinetic Energy ) = 1/2mv²

Ep ( Potential Energy ) = mgh

The Attempted Solution :

Ek = 1/2mv²

= 1/2 x 0.7 x 2²

= 1.4J

Ep = m x g x h

= ( 0.7 kg ) x 10m/s² ( i shall do a round-up ) x h ( unknown )

i was stucked here as i cant get the value of 'h' o.o
