Below find all the details written down. There were two trials labelled 1 and 2 where the only difference was the height h of the pile driver. The video started by measuring the results of trial 1 and then filmed trial 2. Go to the next page to see the questions you need to answer. We have 3 formulae to mix and match. Problem 1 Questions (a) For Trial 1: Calculate PE; (b) What was the work done on the mass to raise it up to 80 cm? (c) What is the kinetic energy (KE1) of the mass when it hits the nail? (d) What is its velocity v1 just before hitting the nail? (e) Is PE2 the (same, double, 4 times, half, a quarter) of PE1? (f) ls v2 the (same, double, 4 times, half, a quarter) of VI ? For the following statements, answer True or False. (g) The total energy imparted to the nail and block system is equal to the original work done on the mass to raise it up. (h) The work done by the mass on the nail is equal to the original work done on the mass to raise it up. (i) The work done on the nail is the force of the mass when it strikes the nail times the distance the nail penetrates into the block. (j) The force on the nail is constant as the nail penetrates into the block and comes to rest. (k) There is thermal energy transferred to the nail and block system. Now that you have answered the T/ F questions, Answer this: (I) Can you use the PE at the beginning to predict how deep the nail gets pounded into the block? e.g. using PE1 = W = F1 x1 and comparing to PE2? Why/Why not
