you can use the idea that the kinetic energy equals the amount of work of friction (Force of friction*d).
Use F(force of friction)= (m(v^2))/2d
...so F=(.005*(360^2))/2*.19= 1705.263 N
you use .005 because the mass was given in grams and the unit of N is kg*m/s so you have to convert 5g to .005kg and 19cm to .19m
A rifle fires a(n) 5 g bullet with a muzzle
velocity of 360 m/s into a block of wood. The bullet comes to rest after it has made a(n)19 cm deep hole in the wood.A rifle fires a(n) 5 g bullet with a muzzle
