i assume the speed here is the velocity? the axe comes to rest so its Vf = 0, with Vi = 60 m/sec = vf-vi = 0-60 = -60m/sec is that right?

Homework Statement The 2kg head of an axe is moving at 60m/sec when it strikes a log. If the blade of an axe penetrates a 20mm into the log, find the average force it exerts. m= 2kg V= 60m/sec d= 20mm or 0.02m Homework Equations F= pFINAL - pINITIAL / time t= d/v The Attempt...
