Question

What is the net work done by the external force one car moving with constant speed?

Answer 1

Here, car is going with constant velocity...

Therefore, acceleration = 0

Because acceleration = dV/dt

––––––––––-––-–-----------------------------

so, no net force acting on car...

Because F = m × a (here, a = 0)

----------------------------------------------------------

so, Work done = 0

Because W = F * d (here, F = 0)

Answer :

Net Work Done = 0 J
