You have plans to create a giant cube-shaped balloon for the hot air balloon race you entered over spring break. If you and the basket are 300 kg, and hot air is about 25% less dense than the atmosphere, how big must your balloon be to lift off the ground?
In order for a balloon launch to be interesting, we will want to tie some sort of payload to the balloon. Payloads can include a video camera, GPS tracking, measurement equipment, etc. If the payload that we plan to attach has a mass of 2.7 kg, what is the minimum volume of our Hydrogen balloon that is needed to lift it into the air?
Consider the pressure on a shot putter's hand as he throws the heavy shot.
a. Calculate the average pressure, in newtons per square meter, exerted on the palm of a shotputter’s hand by the shot if the area of contact is 49.5cm2 and he exerts a force of 790 N on it.
b. What is the ratio of this pressure to the atmospheric pressure?

- What is the pressure at the bottom of a 30 cm long bag of water in a space ship that is in gravity-free space?arrow_forwardAt ground level, the air pressure measured with a barometer is 1000 mb. The barometer is lifted upward by a weather balloon. When the balloon reaches 2 km above the ground, the measured air pressure is 800 mb. Explain why the air pressure decreased. After the balloon goes up another 2 km (now 4 km above the ground), will the measured air pressure be exactly 600 mb, lower than 600 mb, or higher than 600 mb? Explain the reason for your answer. Hint: This can be a little tricky. You need to consider how air density changes as you move upward. See the figure below. If air density does not change as you move upward, then the "block" or air from 2- 4 km weighs the same as the "block" of air from 0 - 2 km and the air pressure will decrease uniformly to be exactly 600 mb at 4 km. If air density changes as you move upward, then the "block" of air from 2 - 4 km will not weigh the same as the block of air from 0 - 2 km and so the air pressure will not be exactly 600 mb at 4 km.arrow_forwardA space shuttle carrying humans and science experiments contains an air ratio similar to (but not the same as) Earth: 77% of the air is a mix of N2 and Ar.
