The magnitude of the vectors F is 21 N, the force on the right is applied at an angle 61° and the the mass of the block is 61 kg. If the surface is frictionless, what is the magnitude of the resulting acceleration?
Answer in units of m/s?.

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.

The magnets would be | n s | and | s n|

The answer is a i think
