Question

Suppose somebody tosses you a raw egg and you catchit.

(a) If the egg has mass m and is heading toward yourhand at speed v, what is the change in its momentum whenyou catch it? What is the impulse from your hand? Does your answerdepend on whether you catch the egg gently or not?

(b) Suppose the time you take to bring the egg to a stop ist. Would you rather catch the egg in such a waythat t is small or large. Why?

(c) How is the average force,F, exerted on the egg related to the time ittakes to catch the egg, t?

Explanation / Answer

          Giventhat the mass of the egg is m           Initialvelocity is v -------------------------------------------------------- (a) The final velocity that reach the hand is v          So the changein momentum is P = [ mv - (-mv) ]                                                               =2mv (b) If time is large then force is small otherwiseforce is large. (c) The acearge force is F = P / t
