A man claims he can safely hold on to a 10.20 kg child in a head-on collision with a relative speed of 123. mi/h lasting for 0.140 s as long as he has his seat belt on. Hint: 1 mi/h = 0.447 m/s (a) Find the magnitude of the momentum of the child.   A man claims he can safely hold on to a 10.20 kg child in a head-on collision with a relative speed of 123. mi/h lasting for 0.140 s as long as he has his seat belt on.  (c) For comparison, calculate the magnitude of force generated by the record weightlifting champion in the 2004 Olympics. He lifted 263 kg. Based on these results, is the man’s claim valid? Explain why or why not.
