Aballoon filled with helium plus air at atmospheric pressure is designed to support a mass of 116 kg (payload +empty balloon). air density is 1.29 kg/m^3, helium plus air density in the balloon is 0.296 kg/m^3, and helium density is 0.179 kg/m^3. ignoring the volume of the payload, find the volume of the balloon. answer in units of m^3.

The slotted link is pinned at o, and as a result of rotation it drives the peg p along the horizontal guide. compute the magnitude of the velocity and acceleration of p along the horizontal guide. compute the magnitudes of the velocity and acceleration of p as a function of θ if θ=(3t) rad, where t is measured in seconds.
