Q. A picture hangs on a nail. The tension T in each string segment is 3.5 N. What is the equilibrant or the upward reaction force of the nail? a. What is the weight of the picture? b.What is the picture's weight?
Q. Amazingly, at the exact distance that you calculated in question 2a (73.5 meters), there was a trampoline! Thinking quickly, I orient myself appropriately and hit the trampoline. If I hit the trampoline at the velocity that you calculated in problem 2 (38.8m/s), and leave it at an angle of 36 degrees from the horizontal, at a velocity of 40 m/s, and am in contact with the trampoline for 0.5 second: (3a.) What is the average acceleration that I felt while in contact with the trampoline? (3b.) Is this velocity (40m/s), at that angle (36 degrees), enough to allow me to clear a spiky wall that is 25 meters away and 15 meter high?
