###### Question:

A helium balloon ride lifts up passengers in a basket. Assume the density of air is 1.28 kg/m and the density of helium in the balloon is 0.18 kg/m. The radius of the balloon (when filled) is R-5 m. The total mass of the empty balloon and basket is my - 124 kg and the total volume is Vn 0.061 m. Assume the average person that gets into the balloon has a mass mp - 70 kg and volume Vp -0.076 m. 1) What is the volume of hellum in the balloon when fully inflated? 381.5 mSubmit You currently have 1 submissions for this question.
