Mass of the hammer (m) = 500 g = 0.5 kg The initial velocity of the hammer (u) = 50 m/s Time is taken by the nail to the stop the hammer (t) = 0.01 s The velocity of the hammer (v) = 0 (since the hammer finally comes to rest) From Newton’s second law of motion f = m (v – u) / t Where f = force f = 0.5 × (0 – 50) / 0.01 f = -2500 N
