A mountain climber carries a barometer which reads 30.1 in Hg at the base of the mountain. After her climb, the barometer reads 26.45 in Hg. Estimate the vertical distance she has climbed if the average air density is taken to be 0.074 lbm/ft3. Neglect the effect of altitude on local gravity.
As shown, a 130 lb bungee jumper wants to jump from the top of a 655 ft high bridge and be able to just touch the water below. Given that the bungee cord has a spring constant of 2.33 lb/ft, what should the bungee cord's relaxed length, l, be for ..
