QUESTION 9 QUESTION 9 Lоndi tаkes а trip tо Pаris with her family in the December hоliday. She is lucky enough to get the chance to climb the Eiffel tower up to the top viewing deck, of which the top of the railing is 276 m above the ground. 9.1. Londi took a selfie at the top viewing deck when her cell phone (mass 170 g) slips out of her hand and falls over the edge of the railing to the ground! 9.1.1 Define the term kinetic energy (2) 9.1.2 Calculate the gravitational potential energy of Londi’s phone the moment it slips out of her hands. (3) 9.2 Halfway down the tower, someone tries to catch the phone as it passes another viewing deck, but it is going too fast to catch. Using the conservation of mechanical energy, calculate the magnitude of the velocity of the phone at this point. (5) 9.3 Convert your answer in Question 9.2 to km.h-1 (2) [12]
