A 3kg mass is observed moving at a constant velocity of 16m/s. What is the net force acting on the mass?
I can find the answer, if someone would just tell me the proper equation for it. Please?
This seems to be asking about Newton’s 1st law - ‘a body will continue moving uniformly in a straight line unless acted upon by an external force’. Your 3kg mass is "moving at a constant velocity of 16m/s", so we can deduce that the net force acting on it is zero.
‘Net force’ means any difference, for example, between friction and a driving force, or between gravitational force and a supporting force.
