a toy train P of mass 3kg,is connected by a string to a wagon Q of mass 2kg.Thulu fastens a cable to P and pulls it with a force of 12N at an angle of 60degrees horizontally.the train moves over a wooden floor A frictional force of 2N act between the engineP and the floor while wagon Q experiencies a frictional force of 1N. calculate the magnitude of accelaration?.calculate the magnitude of the tentionT in the string connecting P and Q?
