Q. A dragonfly flies from point A to point B along the path shown in figure below in 1.50s. If the dragonfly's velocity components at point A are vx= 6.20m/s and vy= 5.11m/s and at point B are vx= 4.05m/s and vy= 8.26 m/s. Find the x component of the dragonfly's average acceleration between A and B. Find the y component of the dragonfly's average acceleration between A and B. Find the magnitude of its average acceleration between those points. Find the direction of its average acceleration between those points.
Q. A spherical balloon has a radius of 8.5 m, and is filled with helium. How large a cargo can it lift, assuming that the skin and structure of the balloon have a mass of 1000 kg? Neglect the bouyant force on the cargo volume itself.
