A small ball of mass m = 5 kg is suspended from
a string of length L = 5 m. The ball revolves
with constant speed v in a horizontal circle of
radius r = 2 m. Find an expression for v and a.

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.

Iwould sure like to answer your question but i honestly just don’t know

What even is this. where is the question
