Kiran runs along a straight road of length 150 m. After reaching at end of the road he runs back to his initial
position along the same straight path. If he takes a total
time of 1 minute for completing his running, find the
average speed and average velocity of Kiran.

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.

Iam looking for this answer too!
