2) You are driving 2018 Honda Civic and are stuck behind 2018 Toyota Tundra. a) What is the increase in kinetic energy of your car as you speed up from 5 m/s to 12 m/s? b) What is the increase in kinetic energy of your car as you speed up from 12 m/s to 19 m/s? c) What do you conclude from (a) and (b)? d) Compare power of both cars 3) In the Empire State Building Run up, Competitors race up the 1576 steps of the empire state building climbing a total vertical distance of 320 m. How much gravitational potential energy does a 70kg racer gain during this race? 4) The maximum energy a bone can absorb without breaking is surprisingly small. For a healthy human of mass 60 Kg (132 pounds), experiments show that the leg bone can absorb about 200J. For what maximum height could a person jump and land upright on both feet without breaking their legs? Assume that all energy is absorbed in leg bones on a rapid landing
