Asked by Sanda

the 5.0 kilogram block shown below is accelerated from rest across a wood floor (coefficient kinetic friction 0.22) by a 40 N pulling force for 3.0 seconds

What us the blocks final velocity/speed?
I am not sure what force i am supposed to calculate??
Answered by bobpursley
if the pulling force is horizontal
netforc=ma
40-5g*.22=ma
solve for a

vf=at
