Question

7. In 1990, Randy Barnea of UCLA set the current world record for the ahot put at 75 feet and 10.25 inchea (23.12 metera). (You can watch the YouTube video!) Aaaume he hurled the 16 pound, ateel ball at an initial angle of 45 above the ground. Further aaaume he releaaed the ahot 2.20 metera above the ground and the total time of flight ia 2.277 aec. Show how to caloulate the maximum height the ahot reached above the releaae point. Verify thia height ia 7.46 metera.11. Soience fiotion ia filled with examplea of large apacecraft or apace atationa that apin on an axia to generate artificial gravity. Many believe NASA ahould incorporate thia into a manned Mara miaaion due to the harmful effecta of zero gravity on the human body. Conaider a apacecraft in the ahape of a apoked wheel with the aurface of the floor 30.0 metera from the axia of rotation. Caloulate the neceaaary rate of rotation (in RPM) in order to create an artificial acceleration equal to the real acceleration due to gravity found on the aurface of Mara
