A steel

A steel hammer with a weight of 0.5 kg hits the nail at a speed of 3 m/s. How deep the nail penetrates the wood if the hammer acts on the nail with an average force of 50N.

Correct result:

x =  45 mm

Solution:

m=0.5 kg v=3 m/s F=50 N  E1=1/2 m v2=1/2 0.5 32=94=2.25 J E1=Fx x1=E1/F=2.25/50=9200=0.045 m x=1000 x1=1000 0.045=45 mm
