  • Question #6f7d1 - Socratic
    675N Here,the kinetic energy of the hammer head got totally converted to the work done in moving the nail through a distance of 10 mm or 0 01 m So, kinetic energy of the hammer during the strike was 1 2 m v^2=1 2×1 5×3^2=6 75J Now,if an average force of F had acted on the nail to move it by 0 01 m,then work done by the force will be (F×0 01)J(using W=F*s) So,we can equate both 6 75=F×0 01
