Two tug boats push on a barge in a bay with mass 61,014kg as seen in the picture below. If one barge pushes east with a force of F1 = 50,597N, one
pushes north with a force of F2 = 32,351N and the third pushes at an angle of
35 degrees above the horizontal with a force of 12,000N. Find the resulting
acceleration of the boat

Ineed extreme for task 2. my student number is 571721. many to whoever solves this correctly, im in debt to you.

Consider an ordinary, helium-filled party balloon with a volume of 2.2 ft3. the lifting force on the balloon due to the outside air is the net resultant of the pressure distribution exerted on the exterior surface of the balloon. using this fact, we can derive archimedes’ principle, namely that the upward force on the balloon is equal to the weight of the air displaced by the balloon. assuming that the balloon is at sea level, where the air density is 0.002377 slug/ft3, calculate the maximum weight that can be lifted by the balloon. note: the molecular weight of air is 28.8 and that of helium is 4.
