Short Answer - Answer with proper Physics terminology. You may use jot notes, diagrams, equations, etc to explain your answer thoroughly. 1. Mr Jack and Mr Grewal decide to go skydiving together. After jumping out of the plane Mr Jack assumes the "spread eagle" position while Mr Grewal goes into the head first diving position. After several minutes of falling, which of them will have a higher speed? Use physics terminology to explain your answer, and comment on the factors that affect the speed. Would the same thing happen if they went skydiving on the moon? Explain. Problems – Answer the following questions showing all relevant work. 1. Mr Grewal is flying his homemade jet horizontally. He decides to accelerate at 8.1 m/s? [S 18° W] for exactly 5.4 s. He notes that he covers a displacement of 540 m [E 15° S] during that time. What was his initial velocity? 2. Mr Gaglardi is flying his homemade airplane to his cottage which is a distance of 395 km [E 18° NJ. He must arrive there in 160 min to study for Physics! After checking the weather channel, he calculates that he must fly at 190 km/h [E 10° SI. What was the wind's velocity?
